Here are some thoughts I had about my code:

• I get the feeling, looking at $alpha = 'abcdefghijklmnopqrstuvwxyz'; that it could be done in some much smarter way, but I can't think what exactly; any ideas?
• I could use an array for the alphabet, @alpha = (a..z); but I can do the equivalent of substr() on an array, what's the equivalent of index() when it comes to arrays?
• This implementation doesn't preserve case, can anyone see an easy way to make it preserve case?
