[code-review] Tie::Hash::RegexKeys

I've created another module intended for CPAN at
http://www.psdt.com/Tie-Hash-RegexKeys-0.01.tar.gz pending review from 
folks here.  This allows you to use regexen as hash keys and operate on 
the elements with matching keys.  It's not fast when you do that, 'cos 
it scans through potentially all the keys, but it can be useful 
anyway.  Looking forward to feedback.
