That assumes you know which Controller to start with.

I've had this same issue recently. The problems IME are case and attributes.
E.g., URIs are all lc() but the corresponding Controller/Action could be any case.

 /foo/bar

might correspond to:

 MyApp::Controller::Foo::Bar->default()

or

 MyApp::Controller::FOO->bar()

or

 MyApp::Controller::foo->BAR()

etc. You have no way of knowing from just a URI, and in my case, that was what
I had to go on in my template. The Catalyst::Dispatcher seems to be the correct
place to interrogate the action map for any given URL, maybe with
get_action_by_path().

Or am I way off base?
