Hey, that worked. Thanks.
Actually, the parens aren't needed, so this works too:
def __init__(self, args=""): self.args = args,
The trailing comma wasn't necessary a while back (pre 2.5?), so
something in Python must have changed. I'd say that it looks a bit
cleaner without the trailing comma, so maybe whatever changed should
get changed back.
