Package details

Summary: A Tie::RefHash subclass with weakened references in the keys

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 objects.
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.
