| 3300 | 1. Enforce API surface and semantic compatibility with 1.9.x branch |
| 3301 | 2. Improve the module's maintainability by reducing the storage |
| 3302 | paths to a single mechanism. |
| 3303 | 3. Use the same single mechanism to support "private" and "user" data. |
| 3304 | 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData) |
| 3305 | 5. Avoid exposing implementation details on user objects (eg. expando properties) |
| 3306 | 6. Provide a clear path for implementation upgrade to WeakMap in 2014 |
