| 3661 Implementation Summary | |
| 3662 | |
| 3663 1. Enforce API surface and semantic compatibility with 1.9.x branch | |
| 3664 2. Improve the module's maintainability by reducing the storage | |
| 3665 paths to a single mechanism. | |
| 3666 3. Use the same single mechanism to support "private" and "user" data. | |
| 3667 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData) | |
| 3668 5. Avoid exposing implementation details on user objects (eg. expando properties) | |
| 3669 6. Provide a clear path for implementation upgrade to WeakMap in 2014 | |
