- 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
