This works poorly in the event that several exit points require cleanup of
some kind. In C, I often favor constructs of the form:

	if (bad) goto bail;


	Log(logger, "something bad happened\n");
	return 0;

Where numerous conditions can move you to the bail-out point. This
is, of course, trumped by an exception in Python.
