Description:
The Tie::RefHash module can be used to access hashes by reference.
This is useful when you index by object, for example.
The problem with Tie::RefHash, and cross indexing, is that sometimes
the index should not contain strong references to the objecs.
Tie::RefHash's internal structures contain strong references to the
key, and provide no convenient means to make those references weak.
This subclass of Tie::RefHash has weak keys, instead of strong ones.
The values are left unaltered, and you'll have to make sure there are
no strong references there yourself.
