Sorry, I wasn't very clear in that sentence.   It's a bit more involved
than this, but I'm looking at applying a controller role (one with actions)
dynamically.   So, the code ends up something like:

package MyApp;

after setup_components => sub {

my $self = shift;
my $controller $self->controller( 'Foo' );
use My::Role::With::Actions;
My::Role::With::Actions->meta->apply( $controller );


Results in:

Composing MooseX::MethodAttributes::Role::Meta::Role::Application onto
instances is unsupported



That makes sense to me -- for one thing Catalyst would not know about the
actions in the role.

My Last years Advent articles might help. It is a introduction to
creating Chained Catalyst actions in Moose::Role(s):

What's stopping you doing this?

There is no reason you can't have actions (from a role) in a base class..

Alternatively, if you want to switch things on and off from config, look at 
CatalystX::Component::Traits.
