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.
