 //	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
