Professional and hobby programmer using maybe a dozen languages on Linux and Windows. Jill of all trades, master of none.
I've been using Perl on and off since the Pink Camel book was published (and I couldn't afford to buy a copy). Although Perl and I have both come a long way since, sometimes on the same road, sometimes separately, I still feel like a beginner. This can be helpful; it keeps me humble and reminds me that there's always something new to learn.
