def foo(a,b,c,x):

        pass

The following calls are equivalent:

    foo(1,2,3, x=0)

    foo(*(1,2,3), x=0)

However, since python allows keyword arguments before star-unpacking, you can also do:

    foo(x=0, *(1, 2, 3))

But removing the unpacking, would result in a syntax error:

     foo(x=0, 1, 2, 3)

This is against the understanding of unpacking, is this intentional?
