For parsed msgs, I had this:
 elif hasattr (msg.msgBody, 'request'):
It occurred to me that this was less abstruse:
 elif 'request' in msg.msgBody:
and by the way, how would you do that with duck-typing?
If I were doing this anew, I probably use a dictionary of functors,
but that's not an option anymore.
