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.
.
Tie::RefHash::Weak 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.
