Paket: libtie-refhash-weak-perl (0.09-2)

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.
