Another possiblity would be to be able to have alternative signatures
for a single function, the first being the one shown in inspection and
for auto-completion, the other one(s?) just creating new references to
the same variables. Like this:
def fun(a, b, c, d=something1, e=something2, f=something3)(_, *args,
# do whatever you need
assert args == b
assert kwargs["d"] == something1
super().fun("foo", *args, e="bar", **kwargs)
I'm not sure what would happen if we didn't provide the same defaults
for `e` in the two signatures (probably an exception).
