[Catalyst] Re: [RHTMLO] RDBO/RHTMLO integration with Catalyst - work in progress

[Peter Karman]

check out Catalyst::Controller::Rose on cpan.

It has a different philosophy than what you've described. But if you find 
features missing that you think would make it more useful, please send me 
patches/tests/docs etc. You might consider writing a new 
Catalyst::Controller::Rose::SomeThing to implement what you're describing with YAML.
