I like this PEP a lot, but your concern is valid. Maybe Brian could modify the PEP slightly to disambiguate. How about using an ellipsis in the argument list to signify suite-based keywords? Examples:
f(...): x = 1
class C(object): x = property(...): doc = "I'm the 'x' property." def fget(self): return self.__x def fset(self, value): self.__x = value def fdel(self): del self.__x
d = dict(...): a = 1 b = 2
I also like the ellipsis idea much better than the original proposal. While I figured out what the original syntax meant after half a minute of staring at it (unlike the thunk proposal which I still can't decode), I couldn't help but feel that I'd like a visual cue that arguments had been omitted. Seeing
f():
gives me only ':' as a tiny clue that arguments have been omitted. And ':' is used in all Python suites, so it doesn't have a good intuition associated with it. Using ellipsis or something similar to indicate that keyword arguments have been omitted would make this much easier for me to read.
