     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
