Never said I wasn't going to do that... but it doesn't really solve the 
problem. I've played with the base class, AFAICT it has the issue that 
you have to say something like this:

    sub myform : Local Form {
        my($self,$c) = @_;
        my $form = $c->form;
        $c->stash->{form_output} = $form->render;

To get the form instantiated and rendered. In the normal case, having it 
as a plugin makes sense because:

    - The form config is automatically resolved per the $c->action
    - The form is loaded during Catalyst preparation
    - The form is rendered automatically via Catalyst View::Whatever

I'm not sure if you've actually tried to use the FormBuilder plugin or 
not. If you can show/hint/link at how these items could be done via a 
base class, and auto-invoked during prepare(), that would be helpful. So 
far I can't find any decent documentation on controller base classes.
