Description : Tie::RefHash subclass with weakened references in the keys
Tie::RefHash 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. The internal
structures of Tie::RefHash 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.
