      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
