This is fixed is #143. Note that this file will cause an AllError to be raised - the NameError was raised while creating the message for the AllError. pep257 can't determine the value of __all__ in this context.

I'm using a tuple, if pep257 cannot determine it, it probably shouldn't recommend that I do what I'm already doing, still a bug as superfluous reporting IMO
