Tie::Hash::Longest - A hash which knows its longest key and value

This module implements a hash which remembers its longest key and value. It avoids rescanning the entire hash whenever possible.
The following methods are available. Call them thus:
tied(%my_hash)->methodname();
longestkey
Return the longest key.
longestvalue
Return the longest value.
