-//	Implementation Summary
-//
-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	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:
-     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-     *
-     * The chainable wrapper methods are:
-     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
-     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

-     * `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
-     * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

-   * Valid examples are:

-   * 10
-   * '10%'

-//	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:
-     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-     *
-     * The chainable wrapper methods are:
