When a question is poorly asked as well as having no code, I can get pretty rude. OTT, though, I will often post a solution just because I can and it's fun.

I also am not immune to posting a solution that is considered Bad Practise. While I see the educational value of PerlMonks and have been downvoted for being casual about it, I also believe that YMMWAV and Buyer Beware always apply. If the OP uses my solution and gets himself in a wringer, he'll learn to get himself out. I find myself doing this especially when the OP hasn't tried to solve the problem by himself. ;-]
