Calling method with multiple named arguments does not raise SyntaxError

It actually fixes a bug unrelated to double ** usage. Eg the following would previously pass without error:

def f(**x):
    print(x)

f(a=1, a=2)

Can you please add a test for that case as well?

foo(a,b) is not supported

closedby smurfixopened 2019-02-23updated 2019-03-26

Python 3.x uses this construct in functools.

>>> a=(1,2)
>>> b=(3,4)
>>> print(*a,*b)
1 2 3 4

MicroPython:

>>> a=(1,2)
>>> b=(3,4)
>>> print(*a,*b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SyntaxError: can't have multiple *x

Supporting this may not be particularly useful, but it should be documented.
