I wouldn't mind seeing one of the early ideas from PEP 340 being resurrected
some day, such that the signature for the special method was "__next__(self,
input)" and for the builtin "next(iterator, input=None)"
That would go hand in hand with the idea of allowing the continue statement to
accept an argument though.
