Sorry but AFAIK Perl on Rails is vaporware. The main reason why the announcements got such a big audience are IMHO depictions of the pathetic development environment at the BBC.

But did anyone ever see any code?

Catalyst is IMHO very TIMTOWTDI flexible (e.g. allowing integration of all main CPAN templating systems) but heavy and requesting much knowledge and planing.

If you are looking for a more Rails like monolithical approach in Perl you may want to have a look at Jifty or Mojo.
