I don't see any mention of it in the PEP but perhaps there is a good reason this isn't allowed. It seems to be perfectly well-defined to me.
Really? There's two single-stars there. One says "accept arbitrary positional arguments and place them in a tuple named args", the second says "don't accept any more positional args". You can't have it both ways, so the compiler complains.

The following works fine to mix keyword-only arguments with arbitrary positional arguments, so I don't see a problem:
def f(*args, kw): pass
Move along, nothing to see here... -- Regards, Benjamin
