+//	2. Improve the module's maintainability by reducing the storage
+//		paths to a single mechanism.
+//	3. Use the same single mechanism to support "private" and "user" data.
+//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+//	5. Avoid exposing implementation details on user objects (eg. expando properties)
+//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

+     * 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 and 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:
+     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+     *
+     * The wrapper `String` methods are:
+     * `replace` and `split`
+     *
+     * The wrapper methods that support shortcut fusion are:

+     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+     *
