+  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

+  4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+  5. Avoid exposing implementation details on user objects (eg. expando properties)
