I think this is a real problem given the frequent convention that you
can freely add fields to json objects with the additional fields to be
ignored.
Unpacking json objects isn't something one does every day, so I
don't think it would be worth adding syntax just for this.
Rather than new syntax, how about a helper function such as:
def call_with_kwds_from(func, kwds):
code = func.__code__
names = code.co_varnames[:code.co_argcount]
func(**{name : kwds[name] for name in names})
Usage example:
def f(a, b):
print("a =", a, "b =", b)
d = {"a": "a_value", "b": "b_value", "c": "something extra"}
call_with_kwds_from(f, d)
