I do that in MyApp::View::TT, as in this example:

http://search.cpan.org/src/KARMAN/Catalyst-Controller-Rose-0.04/t/examples/CatRose/lib/CatRose/View/TT.pm

I like to add virtual methods so that I can call them more easily. I prefer:

 [% mything.dump_data %]

to:

 [% USE Dumper; Dumper.dump_html( mything ); %]

Of course, you have to be careful when adding virtual methods, that you don't step on the
default ones. So I just have a couple I often use (dump_data and as_json).
