I have been bad at keeping up with new versions of Perl.
If there's not a really great need for me to make everything compatible with Perl 5.8, I'd really rather not (and I can't go back any earlier than that at all because proper Unicode support didn't show up until 5.8). If you and nrapallo decide that you really want to stick with 5.8, however (or if I start getting feedback that 5.10 is a major nuisance to get installed for people that want to use this), I do know what I'd technically need to do to yank the 5.10-specific code.
You might also find the following guides to the new 5.10 features informative:

The big things to me were the smart-match, named regular expression, and speed improvements.
