3696 Implementation Summary
3698 1. Enforce API surface and semantic compatibility with 1.9.x branch
3699 2. Improve the module's maintainability by reducing the storage
3700 paths to a single mechanism.
3701 3. Use the same single mechanism to support "private" and "user" data.
3702 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
3703 5. Avoid exposing implementation details on user objects (eg. expando properties)
3704 6. Provide a clear path for implementation upgrade to WeakMap in 2014
