I've used Perl for some time now. I've also dabbled in Java and C++ a couple of years back. I consider Perl my first (programming) lanaguage. By 'first langauge', I'm referring more to the frequency of use rather than competency.

I'm wondering what's a good second programming language to expose oneself to. I'm likely to use that language in a web environment.

I look forward to reading your comments and advice.

As usual, thanks in advance :)

Update: Thanks for your sharing! I was originally looking for something I could learn as an alternative web programming language but I was curious about about Lisp and Scheme and downloaded DrScheme (thanks to broquaint). The web thing can wait. The parentheses are quite fun for now :)
