Perl REs as System Service

[Alexandre Enkerli]

Did anyone try building a System Service (in the "Services" submenu) to 
apply Perl regular expressions on selected text?
What I have in mind is a Perl version of WordService:
<http://home.arcor-online.de/grunenberg/wordservice.html>
So we could have a bunch of preset scripts triggered by keystrokes as 
well as a way to enter one-liners or custom scripts directly from any 
Services-aware app.
I'm not sure about this but it could possibly preserve text styles in 
RTF files...
