By the way, I sometimes hesitate at having an explicit:

        return None

as the last line of a function.  I guess I usually give in writing it, would
it be only as some kind of documentation, but then (being anal myself :-)
I would consider as a style bug not doing it always, if I do it sometimes.
(It would of course always be OK _not_ writing that line for `def's not
meant to return a usable value.)

I wonder a bit.  Is there any common wisdom about this detail?
