Good point, I was really just thinking of lists though.

I was thinking about a use case like this:
supported_suffixes = ['.py', '.pyc', '.pyo']
if sys.platform[:3] == 'win':
supported_suffixes.append('.pyw')
if pathname.endswith(supported_suffixes):
# ...
I realize you could just throw a tuple(supported_suffixes). I don't
know that I've ever needed that specific use case. I don't think it's
too common. Just thinking about avoiding newbie surprises.

I'm ok with this either way. It's easy enough to add later, but hard
to take away.
