/*
	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
