I thik it's a good thing to have some choice between availble solutions. I use a templating system written by a friend of mine. He gave it a name and we are using it for about 2 years.
Yes - it's Yet Another Templating System - but it's the simpliest one i've ever seen and does my job perfectly! Anyway - it's not on CPAN (yet), becous it's not ready for it. I'd like to add some improvements before making it public.

Anyway the most important thing is what you really need and you should focus on that. On the other side porting Template::Toolkit to other languages also seams reasonable - especially becouse it's good for the community (Perl and others as well).
