	// a transform stream is a readable/writable stream where you do
	// something with the data.  Sometimes it's called a "filter",
	// but that's not a great name for it, since that implies a thing where
	// some bits pass through, and others are simply ignored.  (That would
	// be a valid example of a transform, of course.)
	//
	// While the output is causally related to the input, it's not a
	// necessarily symmetric or synchronous transformation.  For example,
	// a zlib stream might take multiple plain-text writes(), and then
	// emit a single compressed chunk some time in the future.
	//
	// Here's how this works:
	//
	// The Transform stream has all the aspects of the readable and writable
	// stream classes.  When you write(chunk), that calls _write(chunk,cb)
	// internally, and returns false if there's a lot of pending writes
	// buffered up.  When you call read(), that calls _read(n) until
	// there's enough pending readable data buffered up.
	//
	// In a transform stream, the written data is placed in a buffer.  When
	// _read(n) is called, it transforms the queued up data, calling the
	// buffered _write cb's as it consumes chunks.  If consuming a single
	// written chunk would result in multiple output chunks, then the first
	// outputted bit calls the readcb, and subsequent chunks just go into
	// the read buffer, and will cause it to emit 'readable' if necessary.
	//
	// This way, back-pressure is actually determined by the reading side,
	// since _read has to be called to start processing a new chunk.  However,
	// a pathological inflate type of transform can cause excessive buffering
	// here.  For example, imagine a stream where every byte of input is
	// interpreted as an integer from 0-255, and then results in that many
	// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
	// 1kb of data being output.  In this case, you could write a very small
	// amount of input, and end up with a very large amount of output.  In
	// such a pathological inflating mechanism, there'd be no way to tell
	// the system to stop doing the transform.  A single 4MB write could
	// cause the system to run out of memory.
	//
	// However, even in such a pathological case, only a single written chunk
	// would be consumed, and then the rest would wait (un-transformed) until
	// the results of the previous transformed chunk were consumed.

	// a transform stream is a readable/writable stream where you do
	// something with the data.  Sometimes it's called a "filter",
	// but that's not a great name for it, since that implies a thing where
	// some bits pass through, and others are simply ignored.  (That would
	// be a valid example of a transform, of course.)
	//
	// While the output is causally related to the input, it's not a
	// necessarily symmetric or synchronous transformation.  For example,
	// a zlib stream might take multiple plain-text writes(), and then
	// emit a single compressed chunk some time in the future.
	//
	// Here's how this works:
	//
	// The Transform stream has all the aspects of the readable and writable
	// stream classes.  When you write(chunk), that calls _write(chunk,cb)
	// internally, and returns false if there's a lot of pending writes
	// buffered up.  When you call read(), that calls _read(n) until
	// there's enough pending readable data buffered up.
	//
	// In a transform stream, the written data is placed in a buffer.  When
	// _read(n) is called, it transforms the queued up data, calling the
	// buffered _write cb's as it consumes chunks.  If consuming a single
	// written chunk would result in multiple output chunks, then the first
	// outputted bit calls the readcb, and subsequent chunks just go into
	// the read buffer, and will cause it to emit 'readable' if necessary.
	//
	// This way, back-pressure is actually determined by the reading side,
	// since _read has to be called to start processing a new chunk.  However,
	// a pathological inflate type of transform can cause excessive buffering
	// here.  For example, imagine a stream where every byte of input is
	// interpreted as an integer from 0-255, and then results in that many
	// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
	// 1kb of data being output.  In this case, you could write a very small
	// amount of input, and end up with a very large amount of output.  In
	// such a pathological inflating mechanism, there'd be no way to tell
	// the system to stop doing the transform.  A single 4MB write could
	// cause the system to run out of memory.
	//
	// However, even in such a pathological case, only a single written chunk
	// would be consumed, and then the rest would wait (un-transformed) until
	// the results of the previous transformed chunk were consumed.

	     * Creates a `lodash` object which wraps `value` to enable implicit method
	     * chain sequences. Methods that operate on and return arrays, collections,
	     * and functions can be chained together. Methods that retrieve a single value
	     * or may return a primitive value will automatically end the chain sequence
	     * and return the unwrapped value. Otherwise, the value must be unwrapped
	     * with `_#value`.
	     *
	     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
	     * enabled using `_.chain`.
	     *
	     * The execution of chained methods is lazy, that is, it's deferred until
	     * `_#value` is implicitly or explicitly called.
	     *
	     * Lazy evaluation allows several methods to support shortcut fusion.
	     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
	     * the creation of intermediate arrays and can greatly reduce the number of
	     * iteratee executions. Sections of a chain sequence qualify for shortcut
	     * fusion if the section is applied to an array of at least `200` elements
	     * and any iteratees accept only one argument. The heuristic for whether a
	     * section qualifies for shortcut fusion is subject to change.
	     *
	     * Chaining is supported in custom builds as long as the `_#value` method is
	     * directly or indirectly included in the build.
	     *
	     * In addition to lodash methods, wrappers have `Array` and `String` methods.
	     *
	     * The wrapper `Array` methods are:

	     * The wrapper `String` methods are:
	     * `replace` and `split`

	     * The wrapper methods that support shortcut fusion are:

	     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,

	 * @name Lazy.js
	 *
	 * @fileOverview
	 * Lazy.js is a lazy evaluation library for JavaScript.
	 *
	 * This has been done before. For examples see:
	 *
	 * - [wu.js](http://fitzgen.github.io/wu.js/)
	 * - [Linq.js](http://linqjs.codeplex.com/)
	 * - [from.js](https://github.com/suckgamoni/fromjs/)
	 * - [IxJS](http://rx.codeplex.com/)
	 * - [sloth.js](http://rfw.name/sloth.js/)
	 *
	 * However, at least at present, Lazy.js is faster (on average) than any of
	 * those libraries. It is also more complete, with nearly all of the
	 * functionality of [Underscore](http://underscorejs.org/) and
	 * [Lo-Dash](http://lodash.com/).
	 *
	 * Finding your way around the code
	 * --------------------------------
	 *
	 * At the heart of Lazy.js is the {@link Sequence} object. You create an initial
	 * sequence using {@link Lazy}, which can accept an array, object, or string.
	 * You can then "chain" together methods from this sequence, creating a new
	 * sequence with each call.
	 *
	 * Here's an example:
	 *
	 *     var data = getReallyBigArray();
	 *
	 *     var statistics = Lazy(data)
	 *       .map(transform)
	 *       .filter(validate)
	 *       .reduce(aggregate);
	 *
	 * {@link Sequence} is the foundation of other, more specific sequence types.
	 *
	 * An {@link ArrayLikeSequence} provides indexed access to its elements.
	 *
	 * An {@link ObjectLikeSequence} consists of key/value pairs.
	 *
	 * A {@link StringLikeSequence} is like a string (duh): actually, it is an
	 * {@link ArrayLikeSequence} whose elements happen to be characters.
	 *
	 * An {@link AsyncSequence} is special: it iterates over its elements
	 * asynchronously (so calling `each` generally begins an asynchronous loop and
	 * returns immediately).
	 *
	 * For more information
	 * --------------------
	 *
	 * I wrote a blog post that explains a little bit more about Lazy.js, which you
	 * can read [here](http://philosopherdeveloper.com/posts/introducing-lazy-js.html).
	 *
	 * You can also [create an issue on GitHub](https://github.com/dtao/lazy.js/issues)
	 * if you have any issues with the library. I work through them eventually.

	   * The `Sequence` object provides a unified API encapsulating the notion of
	   * zero or more consecutive elements in a collection, stream, etc.
	   *
	   * Lazy evaluation
	   * ---------------
	   *
	   * Generally speaking, creating a sequence should not be an expensive operation,
	   * and should not iterate over an underlying source or trigger any side effects.
	   * This means that chaining together methods that return sequences incurs only
	   * the cost of creating the `Sequence` objects themselves and not the cost of
	   * iterating an underlying data source multiple times.
	   *
	   * The following code, for example, creates 4 sequences and does nothing with
	   * `source`:
	   *
	   *     var seq = Lazy(source) // 1st sequence
	   *       .map(func)           // 2nd
	   *       .filter(pred)        // 3rd
	   *       .reverse();          // 4th
	   *
	   * Lazy's convention is to hold off on iterating or otherwise *doing* anything
	   * (aside from creating `Sequence` objects) until you call `each`:
	   *
	   *     seq.each(function(x) { console.log(x); });
	   *
	   * Defining custom sequences
	   * -------------------------
	   *
	   * Defining your own type of sequence is relatively simple:
	   *
	   * 1. Pass a *method name* and an object containing *function overrides* to
	   *    {@link Sequence.define}. If the object includes a function called `init`,
	   *    this function will be called upon initialization.
	   * 2. The object should include at least either a `getIterator` method or an
	   *    `each` method. The former supports both asynchronous and synchronous
	   *    iteration, but is slightly more cumbersome to implement. The latter
	   *    supports synchronous iteration and can be automatically implemented in
	   *    terms of the former. You can also implement both if you want, e.g. to
	   *    optimize performance. For more info, see {@link Iterator} and
	   *    {@link AsyncSequence}.
	   *
	   * As a trivial example, the following code defines a new method, `sample`,
	   * which randomly may or may not include each element from its parent.
	   *
	   *     Lazy.Sequence.define("sample", {
	   *       each: function(fn) {
	   *         return this.parent.each(function(e) {
	   *           // 50/50 chance of including this element.
	   *           if (Math.random() > 0.5) {
	   *             return fn(e);
	   *           }
	   *         });
	   *       }
	   *     });
	   *
	   * (Of course, the above could also easily have been implemented using
	   * {@link #filter} instead of creating a custom sequence. But I *did* say this
	   * was a trivial example, to be fair.)
	   *
	   * Now it will be possible to create this type of sequence from any parent
	   * sequence by calling the method name you specified. In other words, you can
	   * now do this:
	   *
	   *     Lazy(arr).sample();
	   *     Lazy(arr).map(func).sample();
	   *     Lazy(arr).map(func).filter(pred).sample();
	   *
	   * Etc., etc.

	   * An `ArrayLikeSequence` is a {@link Sequence} that provides random access to
	   * its elements. This extends the API for iterating with the additional methods
	   * {@link #get} and {@link #length}, allowing a sequence to act as a "view" into
	   * a collection or other indexed data source.
	   *
	   * The initial sequence created by wrapping an array with `Lazy(array)` is an
	   * `ArrayLikeSequence`.
	   *
	   * All methods of `ArrayLikeSequence` that conceptually should return
	   * something like a array (with indexed access) return another
	   * `ArrayLikeSequence`, for example:
	   *
	   * - {@link Sequence#map}
	   * - {@link ArrayLikeSequence#slice}
	   * - {@link Sequence#take} and {@link Sequence#drop}
	   * - {@link Sequence#reverse}
	   *
	   * The above is not an exhaustive list. There are also certain other cases
	   * where it might be possible to return an `ArrayLikeSequence` (e.g., calling
	   * {@link Sequence#concat} with a single array argument), but this is not
	   * guaranteed by the API.
	   *
	   * Note that in many cases, it is not possible to provide indexed access
	   * without first performing at least a partial iteration of the underlying
	   * sequence. In these cases an `ArrayLikeSequence` will not be returned:
	   *
	   * - {@link Sequence#filter}
	   * - {@link Sequence#uniq}
	   * - {@link Sequence#union}
	   * - {@link Sequence#intersect}
	   *
	   * etc. The above methods only return ordinary {@link Sequence} objects.
	   *
	   * Defining custom array-like sequences
	   * ------------------------------------
	   *
	   * Creating a custom `ArrayLikeSequence` is essentially the same as creating a
	   * custom {@link Sequence}. You just have a couple more methods you need to
	   * implement: `get` and (optionally) `length`.
	   *
	   * Here's an example. Let's define a sequence type called `OffsetSequence` that
	   * offsets each of its parent's elements by a set distance, and circles back to
	   * the beginning after reaching the end. **Remember**: the initialization
	   * function you pass to {@link #define} should always accept a `parent` as its
	   * first parameter.
	   *
	   *     ArrayLikeSequence.define("offset", {
	   *       init: function(parent, offset) {
	   *         this.offset = offset;
	   *       },
	   *
	   *       get: function(i) {
	   *         return this.parent.get((i + this.offset) % this.parent.length());
	   *       }
	   *     });
	   *
	   * It's worth noting a couple of things here.
	   *
	   * First, Lazy's default implementation of `length` simply returns the parent's
	   * length. In this case, since an `OffsetSequence` will always have the same
	   * number of elements as its parent, that implementation is fine; so we don't
	   * need to override it.
	   *
	   * Second, the default implementation of `each` uses `get` and `length` to
	   * essentially create a `for` loop, which is fine here. If you want to implement
	   * `each` your own way, you can do that; but in most cases (as here), you can
	   * probably just stick with the default.
	   *
	   * So we're already done, after only implementing `get`! Pretty easy, huh?
	   *
	   * Now the `offset` method will be chainable from any `ArrayLikeSequence`. So
	   * for example:
	   *
	   *     Lazy([1, 2, 3]).map(mapFn).offset(3);
	   *
	   * ...will work, but:
	   *
	   *     Lazy([1, 2, 3]).filter(mapFn).offset(3);
	   *
	   * ...will not (because `filter` does not return an `ArrayLikeSequence`).
	   *
	   * (Also, as with the example provided for defining custom {@link Sequence}
	   * types, this example really could have been implemented using a function
	   * already available as part of Lazy.js: in this case, {@link Sequence#map}.)
	   *
	   * @public
	   * @constructor
	   *
	   * @examples
	   * Lazy([1, 2, 3])                    // instanceof Lazy.ArrayLikeSequence

	   * sequence. Note that some sequence types may not support asynchronous
	   * iteration.
	   *
	   * Returning values
	   * ----------------
	   *
	   * Because of its asynchronous nature, an `AsyncSequence` cannot be used in the
	   * same way as other sequences for functions that return values directly (e.g.,
	   * `reduce`, `max`, `any`, even `toArray`).
	   *
	   * Instead, these methods return an `AsyncHandle` whose `onComplete` method
	   * accepts a callback that will be called with the final result once iteration
	   * has finished.
	   *
	   * Defining custom asynchronous sequences
	   * --------------------------------------
	   *
	   * There are plenty of ways to define an asynchronous sequence. Here's one.
	   *
	   * 1. First, implement an {@link Iterator}. This is an object whose prototype
	   *    has the methods {@link Iterator#moveNext} (which returns a `boolean`) and
	   *    {@link current} (which returns the current value).
	   * 2. Next, create a simple wrapper that inherits from `AsyncSequence`, whose
	   *    `getIterator` function returns an instance of the iterator type you just
	   *    defined.
	   *
	   * The default implementation for {@link #each} on an `AsyncSequence` is to
	   * create an iterator and then asynchronously call {@link Iterator#moveNext}
	   * (using `setImmediate`, if available, otherwise `setTimeout`) until the iterator
	   * can't move ahead any more.
	   *
	   * @public
	   * @constructor
	   * @param {Sequence} parent A {@link Sequence} to wrap, to expose asynchronous
	   *     iteration.
	   * @param {number=} interval How many milliseconds should elapse between each
	   *     element when iterating over this sequence. If this argument is omitted,
	   *     asynchronous iteration will be executed as fast as possible.

	 * @name Lazy.js
	 *
	 * @fileOverview
	 * Lazy.js is a lazy evaluation library for JavaScript.
	 *
	 * This has been done before. For examples see:
	 *
	 * - [wu.js](http://fitzgen.github.io/wu.js/)
	 * - [Linq.js](http://linqjs.codeplex.com/)
	 * - [from.js](https://github.com/suckgamoni/fromjs/)
	 * - [IxJS](http://rx.codeplex.com/)
	 * - [sloth.js](http://rfw.name/sloth.js/)
	 *
	 * However, at least at present, Lazy.js is faster (on average) than any of
	 * those libraries. It is also more complete, with nearly all of the
	 * functionality of [Underscore](http://underscorejs.org/) and
	 * [Lo-Dash](http://lodash.com/).
	 *
	 * Finding your way around the code
	 * --------------------------------
	 *
	 * At the heart of Lazy.js is the {@link Sequence} object. You create an initial
	 * sequence using {@link Lazy}, which can accept an array, object, or string.
	 * You can then "chain" together methods from this sequence, creating a new
	 * sequence with each call.
	 *
	 * Here's an example:
	 *
	 *     var data = getReallyBigArray();
	 *
	 *     var statistics = Lazy(data)
	 *       .map(transform)
	 *       .filter(validate)
	 *       .reduce(aggregate);
	 *
	 * {@link Sequence} is the foundation of other, more specific sequence types.
	 *
	 * An {@link ArrayLikeSequence} provides indexed access to its elements.
	 *
	 * An {@link ObjectLikeSequence} consists of key/value pairs.
	 *
	 * A {@link StringLikeSequence} is like a string (duh): actually, it is an
	 * {@link ArrayLikeSequence} whose elements happen to be characters.
	 *
	 * An {@link AsyncSequence} is special: it iterates over its elements
	 * asynchronously (so calling `each` generally begins an asynchronous loop and
	 * returns immediately).
	 *
	 * For more information
	 * --------------------
	 *
	 * I wrote a blog post that explains a little bit more about Lazy.js, which you
	 * can read [here](http://philosopherdeveloper.com/posts/introducing-lazy-js.html).
	 *
	 * You can also [create an issue on GitHub](https://github.com/dtao/lazy.js/issues)
	 * if you have any issues with the library. I work through them eventually.

	   * The `Sequence` object provides a unified API encapsulating the notion of
	   * zero or more consecutive elements in a collection, stream, etc.
	   *
	   * Lazy evaluation
	   * ---------------
	   *
	   * Generally speaking, creating a sequence should not be an expensive operation,
	   * and should not iterate over an underlying source or trigger any side effects.
	   * This means that chaining together methods that return sequences incurs only
	   * the cost of creating the `Sequence` objects themselves and not the cost of
	   * iterating an underlying data source multiple times.
	   *
	   * The following code, for example, creates 4 sequences and does nothing with
	   * `source`:
	   *
	   *     var seq = Lazy(source) // 1st sequence
	   *       .map(func)           // 2nd
	   *       .filter(pred)        // 3rd
	   *       .reverse();          // 4th
	   *
	   * Lazy's convention is to hold off on iterating or otherwise *doing* anything
	   * (aside from creating `Sequence` objects) until you call `each`:
	   *
	   *     seq.each(function(x) { console.log(x); });
	   *
	   * Defining custom sequences
	   * -------------------------
	   *
	   * Defining your own type of sequence is relatively simple:
	   *
	   * 1. Pass a *method name* and an object containing *function overrides* to
	   *    {@link Sequence.define}. If the object includes a function called `init`,
	   *    this function will be called upon initialization.
	   * 2. The object should include at least either a `getIterator` method or an
	   *    `each` method. The former supports both asynchronous and synchronous
	   *    iteration, but is slightly more cumbersome to implement. The latter
	   *    supports synchronous iteration and can be automatically implemented in
	   *    terms of the former. You can also implement both if you want, e.g. to
	   *    optimize performance. For more info, see {@link Iterator} and
	   *    {@link AsyncSequence}.
	   *
	   * As a trivial example, the following code defines a new method, `sample`,
	   * which randomly may or may not include each element from its parent.
	   *
	   *     Lazy.Sequence.define("sample", {
	   *       each: function(fn) {
	   *         return this.parent.each(function(e) {
	   *           // 50/50 chance of including this element.
	   *           if (Math.random() > 0.5) {
	   *             return fn(e);
	   *           }
	   *         });
	   *       }
	   *     });
	   *
	   * (Of course, the above could also easily have been implemented using
	   * {@link #filter} instead of creating a custom sequence. But I *did* say this
	   * was a trivial example, to be fair.)
	   *
	   * Now it will be possible to create this type of sequence from any parent
	   * sequence by calling the method name you specified. In other words, you can
	   * now do this:
	   *
	   *     Lazy(arr).sample();
	   *     Lazy(arr).map(func).sample();
	   *     Lazy(arr).map(func).filter(pred).sample();
	   *
	   * Etc., etc.

	   * An `ArrayLikeSequence` is a {@link Sequence} that provides random access to
	   * its elements. This extends the API for iterating with the additional methods
	   * {@link #get} and {@link #length}, allowing a sequence to act as a "view" into
	   * a collection or other indexed data source.
	   *
	   * The initial sequence created by wrapping an array with `Lazy(array)` is an
	   * `ArrayLikeSequence`.
	   *
	   * All methods of `ArrayLikeSequence` that conceptually should return
	   * something like a array (with indexed access) return another
	   * `ArrayLikeSequence`, for example:
	   *
	   * - {@link Sequence#map}
	   * - {@link ArrayLikeSequence#slice}
	   * - {@link Sequence#take} and {@link Sequence#drop}
	   * - {@link Sequence#reverse}
	   *
	   * The above is not an exhaustive list. There are also certain other cases
	   * where it might be possible to return an `ArrayLikeSequence` (e.g., calling
	   * {@link Sequence#concat} with a single array argument), but this is not
	   * guaranteed by the API.
	   *
	   * Note that in many cases, it is not possible to provide indexed access
	   * without first performing at least a partial iteration of the underlying
	   * sequence. In these cases an `ArrayLikeSequence` will not be returned:
	   *
	   * - {@link Sequence#filter}
	   * - {@link Sequence#uniq}
	   * - {@link Sequence#union}
	   * - {@link Sequence#intersect}
	   *
	   * etc. The above methods only return ordinary {@link Sequence} objects.
	   *
	   * Defining custom array-like sequences
	   * ------------------------------------
	   *
	   * Creating a custom `ArrayLikeSequence` is essentially the same as creating a
	   * custom {@link Sequence}. You just have a couple more methods you need to
	   * implement: `get` and (optionally) `length`.
	   *
	   * Here's an example. Let's define a sequence type called `OffsetSequence` that
	   * offsets each of its parent's elements by a set distance, and circles back to
	   * the beginning after reaching the end. **Remember**: the initialization
	   * function you pass to {@link #define} should always accept a `parent` as its
	   * first parameter.
	   *
	   *     ArrayLikeSequence.define("offset", {
	   *       init: function(parent, offset) {
	   *         this.offset = offset;
	   *       },
	   *
	   *       get: function(i) {
	   *         return this.parent.get((i + this.offset) % this.parent.length());
	   *       }
	   *     });
	   *
	   * It's worth noting a couple of things here.
	   *
	   * First, Lazy's default implementation of `length` simply returns the parent's
	   * length. In this case, since an `OffsetSequence` will always have the same
	   * number of elements as its parent, that implementation is fine; so we don't
	   * need to override it.
	   *
	   * Second, the default implementation of `each` uses `get` and `length` to
	   * essentially create a `for` loop, which is fine here. If you want to implement
	   * `each` your own way, you can do that; but in most cases (as here), you can
	   * probably just stick with the default.
	   *
	   * So we're already done, after only implementing `get`! Pretty easy, huh?
	   *
	   * Now the `offset` method will be chainable from any `ArrayLikeSequence`. So
	   * for example:
	   *
	   *     Lazy([1, 2, 3]).map(mapFn).offset(3);
	   *
	   * ...will work, but:
	   *
	   *     Lazy([1, 2, 3]).filter(mapFn).offset(3);
	   *
	   * ...will not (because `filter` does not return an `ArrayLikeSequence`).
	   *
	   * (Also, as with the example provided for defining custom {@link Sequence}
	   * types, this example really could have been implemented using a function
	   * already available as part of Lazy.js: in this case, {@link Sequence#map}.)
	   *
	   * @public
	   * @constructor
	   *
	   * @examples
	   * Lazy([1, 2, 3])                    // instanceof Lazy.ArrayLikeSequence

	   * sequence. Note that some sequence types may not support asynchronous
	   * iteration.
	   *
	   * Returning values
	   * ----------------
	   *
	   * Because of its asynchronous nature, an `AsyncSequence` cannot be used in the
	   * same way as other sequences for functions that return values directly (e.g.,
	   * `reduce`, `max`, `any`, even `toArray`).
	   *
	   * Instead, these methods return an `AsyncHandle` whose `onComplete` method
	   * accepts a callback that will be called with the final result once iteration
	   * has finished.
	   *
	   * Defining custom asynchronous sequences
	   * --------------------------------------
	   *
	   * There are plenty of ways to define an asynchronous sequence. Here's one.
	   *
	   * 1. First, implement an {@link Iterator}. This is an object whose prototype
	   *    has the methods {@link Iterator#moveNext} (which returns a `boolean`) and
	   *    {@link current} (which returns the current value).
	   * 2. Next, create a simple wrapper that inherits from `AsyncSequence`, whose
	   *    `getIterator` function returns an instance of the iterator type you just
	   *    defined.
	   *
	   * The default implementation for {@link #each} on an `AsyncSequence` is to
	   * create an iterator and then asynchronously call {@link Iterator#moveNext}
	   * (using `setImmediate`, if available, otherwise `setTimeout`) until the iterator
	   * can't move ahead any more.
	   *
	   * @public
	   * @constructor
	   * @param {Sequence} parent A {@link Sequence} to wrap, to expose asynchronous
	   *     iteration.
	   * @param {number=} interval How many milliseconds should elapse between each
	   *     element when iterating over this sequence. If this argument is omitted,
	   *     asynchronous iteration will be executed as fast as possible.
