I mostly use ActivePerl under Windows.
I've only done two "real" thing in Perl so far, one using CGI.pm to do dynamic generation of webpages and a little thingy to compare DNS against DHCP information. And of course several little thingies to do a repetitive task, or nasty things, with ASCII files.
Oh, I've now played a little with use Tk; and done a little thing that lists the available network shares on a list of Windows computers and displays it nicely. Learned a lot and was both disappointed and impressed when it was only thirty-some lines after I'd removed all the notes and testing/debugging cruft. It's posted in Win32 Stuff in the Code Catacombs.
I'm reminded of the day my daughter came in, looked over my shoulder at some Perl 4 code, and said, "What is that, swearing?"
