That is exactly the case for Python functions.

 >>> def f(a,b):
	c,d = 3,4
	print(locals())

 >>> f.__code__.co_varnames # local names
('a', 'b', 'c', 'd')
 >>> f(1,2)
{'a': 1, 'c': 3, 'b': 2, 'd': 4}

The requirement for a function call is that all parameters get an 
assignment and that all args are used in assignments (either directly by 
position or keyname or as part of a *args or **kwds assignment).
