Since auto is internally just another step in _DISPATCH (Catalyst gets to it 
by calling forward and everything) detaching from it behaves as you'd expect 
-- the action you detach to is run, and so is end, and the current dispatch 
(including the rest of auto and running $c->action) is abandoned. So, possibly 
there are *cleaner* ways to deal with situations like that (often involving 
Chained), but if you want to do it, it shouldn't break on you.
