After having seen the entry on HN, it took about 5 minutes and the print version of the book was ordered :). I've been using Perl on and off for more than 10 years, mostly for sysadmin and data munging stuff, and I'm always on the lookout for good short scripts. I'm looking forward to browse through the book (I still prefer print versions). I've bookmarked your blog as well.
