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