  //
  //	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
