Thats incredibly cool stuff. Two bugs though, stuff to the left of a => should be displayed as a string, and stuff inside a qwxx should also be displayed as strings, currently it's highlighting the sigils of variables inside one.
Comment on Re: (Client side) Perl Syntax Highlighter
These are not bugs, but lack of features ;-)
Regexes and qwx stuff are not implemented yet, if anyone has a good suggestion on how to match stuff like qw{}, please let me know.
