I was wondering if anyone had done comparisions between some of the
major templating engines. I'm thinking specifically of Template Toolkit,
Mason, HTML::Template, and EmbPerl. I currently use HTML::Template, and
am happy with it. But I am always open to suggestions.

I really like the fact that templates can be compiled to perl code &
cached. Any others besides Mason & EmbPerl (and TT in the near future)?
