Mmm... under five.grok, at least, it seems that the view cannot be
published anyway. I have a view like this:
from five import grok
from zope.interface import Interface
import pdb; pdb.set_trace( )
However, I can't traverse to @@debug anywhere. This used to work when
this was just grok.View (which now gives an error).
