For the record, Catalyst & Maypole are Perl ports of the Ruby on Rails idea.

Except that they're not.

Maypole was out for some time before Rails hit the streets. Indeed there was a perl.com article on it before Rails was out ;-)

Catalyst has certainly stolen some stuff from Rails, but it's as much an evolution of Maypole as it is a version of Rails.

(Not that Rails isn't an excellent little framework - and Ruby an excellent language :-)
