With two exceptions, nice suggestions if feasible.
>>> def foo(*args=None): pass
SyntaxError: * argument cannot have default value
>>> def foo(**kwargs=None): pass
SyntaxError: ** argument cannot have default value
Good.
>>> foo(*args=[0])
SyntaxError: cannot assign to iterable argument unpacking
>>> foo(**args={"a": None})
SyntaxError: cannot assign to keyword argument unpacking
Incomprehensible. It seems to me that these should have same message as first
two; message should not depend on proposed default.
