  3688 	Implementation Summary
       
  3689 
       
  3690 	1. Enforce API surface and semantic compatibility with 1.9.x branch
       
  3691 	2. Improve the module's maintainability by reducing the storage
       
  3692 		paths to a single mechanism.
       
  3693 	3. Use the same single mechanism to support "private" and "user" data.
       
  3694 	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
       
  3695 	5. Avoid exposing implementation details on user objects (eg. expando properties)
       
  3696 	6. Provide a clear path for implementation upgrade to WeakMap in 2014
