Why not override MyApp::View::MyView->process() and put your Perl code
layer in there? What I do is have ->process() build up pieces of HTML,
like tables, forms, etc, with whatever external module I see fit,
based on the stash data. Then I stuff them back into the stash and use
the template only for layouting those pre-built pieces.
