you know there are several mature mvc frameworks already right? catalyst for example..
Just for starters though: perl 5.12 language features, Moose, Plack, perlbrew, Task::Kensho, the Modern Perl and Enlightened Perl movements, the Padre IDE, Strawberry Perl. That's maybe 0.0001% of what's going on.
I bet there's a tonne more work going into Perl modules than Ruby gems...
Edit: I might add that you could describe the situation as that parts of Perl 6 has been "backported" to Perl 5. Moose seems to take over the Perl world, like testing did a decade ago. The fun part is the extensibility of the language.
(Update: I should note that I've been toying with Mojolicious for a private project in the last few weeks, and quite enjoyed the experience. Hence "done right").
