//	1. Enforce API surface and semantic compatibility with 1.9.x branch

//	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

 * number of iteratee executions.
 *
 * 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`, `reverse`, `shift`, `slice`, `sort`,
 * `splice`, and `unshift`
 *
