Hey, nice, didn't know about SimpleNamespace. I was about to suggest
collections.namedtuple but that one is probably more than Neal asked for.
Alternatively, you can still put attributes on a function, so this works as
well (but I
think it's rather ugly):
thing = lambda: None
thing.attr = 42
vars(thing) # {'attr': 42}
