in reply to Declaring an Array Using Character Classes
The replies you've already received do a great job of creating the array you asked for. I'm a little bit curious on what your intended use for this array is? I ask because I'm trying to imagine a use for this, and the only one I could come up with would be something like a password (or other random string) generator. On the chance that is what you're doing, you may want to check out CPAN modules like the following:
The list is actually quite lengthy, so I refer you to the recent research of Neil Bowers: CPAN modules for generating passwords
My apologies of course if I'm completely off the mark, but again I'm curious about your use case if you'd like to share.
