This is used in the WeakValueDictionary to avoid having to create a function object for each key stored in the mapping. A shared callback object can use the 'key' attribute of a KeyedRef instead of getting a reference to the key from an enclosing scope.

Entries in the dictionary will be discarded when there is no longer a strong reference to the key. This can be used to associate additional data with an object owned by other parts of an application without adding attributes to those objects.
