Re: regex of hash key on the fly

Tie::Hash::Regex provides that interface you want, but internally loops over all the keys. That's inevitable if you use a regex. If your concern is efficiency, Tie::Hash::Regex is not going to help.

If I correctly understand what you are trying to do, you could actually store your data in a format that's more useful to you, eliminating the need for regexs entirely.

$hash{$serial}{''} = ...;
$hash{$serial}{O}  = ...;
$hash{$serial}{R}  = ...;

Like a ton of bricks it hit me that is probably the best thing to do. Strip the (O) or (R) and add it into the array so that I can keep track of that information.	[reply]
