Regression: unpack list and keyword parameters fails as syntax error

What steps will reproduce the problem?

def unpack(x,y):
    return (x,y)
assert unpack(*(1,2))==(1,2)
assert unpack(**{'x':1, 'y':2})==(1,2)
class Un:
  def unpack(self, x, y):
    return (x,y)
assert Un().unpack(*(1,2))==(1,2)
assert Un().unpack(**{'x':1, 'y':2})==(1,2)
print('OK')

What is the expected output? What do you see instead?
