I would like to point out that the method from the above-quoted IRC
conversation is *NOT* what I'd like to see added in Python. I'd much
prefer something like in the linked python-dev mail.
_However_, Twisted is supposed to work on 2.2, 2.3, and 2.4, none of
which have the hypothetical new exception hierarchy that doesn't suck.
Therefore, IMO, the best solution to fix things in Twisted, that will
both work right now, and forwardly compatible, is to do as above and
require that all except:'s (and except Exception's) are preceded by an
