10 Implementation Summary
11  
12 1. Enforce API surface and semantic compatibility with 1.9.x branch
13 2. Improve the module's maintainability by reducing the storage
14 paths to a single mechanism.
15 3. Use the same single mechanism to support "private" and "user" data.
16 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
17 5. Avoid exposing implementation details on user objects (eg. expando properties)
18 6. Provide a clear path for implementation upgrade to WeakMap in 2014
