libtie-aliashash-perl - 1.02-1.1 main

Tie::AliasHash creates hashes that can have multiple keys for a single value.
This means that some keys are just 'aliases' for other keys.
.
Two aliases keys share the same value, so that fetching either of them will
always return the same value, and storing a value in one of them will change
both.
.
The only difference between the two keys is that aliased key is not reported
by keys() and each().
