+       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
