+This mechanism is used by L<Catalyst::Action::RenderView> to forward

+It should be noted that whilst forward is useful, it is not the only way
+of calling other code in Catalyst. Forward just gives you stats in the debug
+screen, wraps the code you're calling in an exception handler and localises
+C<< $c->request->args >>.

+If you don't want or need these features then it's perfectly acceptable
