While you're proposing expanding the domain of the * construct of function calling to other parts of python, I'd also like to suggest the following features, to make the ** construct also applicable to the rest of the language. To be read with an 70% wink. (I wouldn't be *un*happy if these were in python, but I am not seriously proposing these features for inclusion): Dict unpacking, parallels current sequence unpacking:
d = {'foo': 1, 'bar': 2} {'foo': x, 'bar': y} = d x, y (1, 2)
Dict interpolation, similar to sequence interpolation and keyword interpolation in function calls:
d = {'foo': 1, 'bar': 2} d2 = {'baz': 3, **d} d2 {'baz': 3, 'foo': 1, 'bar': 2}
Combining the two:
d = {'foo': 1, 'bar': 2, 'baz': 3} {'foo': x, 'bar': y, **d2} = d x, y, d2 (1, 2, {'baz': 3})
