I use this form in my real coding.

More precisely I asked about the following thing.

Let

def foo(*args, **kw): ...

So

in call: foo(x=2,y=3, a,b,c)
        args = [a,b,c] and kw = {'x':2, 'y':3}

in call: foo(a,b,c, x=2, y=3)
        args = [a,b,c] and kw = {'x':2, 'y':3} too.

It's just simmetrical form of calling syntax.
