-//	Implementation Summary

-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	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

 complex python objects that can be serialized/deserialized to and from strings,

 <p><strong>versionedobj</strong> also provides a versioning mechanism, to track changes in object
 structure across time, and to migrate between different object versions.</p>
