I've been testing Catalyst for a while, and it seems to be a very nice framework for web applications. I think it has the same power and robustness other widely used frameworks have, and it is written in Perl.
It is powerful enough for developing a big project, and simple enough to write a simple application. Its plugin architeture Just Workstm and there's a plenty of already written plugins around.
Kudos to Catalyst development team! Keep the good work!
