I don't find it that surprising. If you write f(b=2, a=1), you are also passing arguments "not in order", but it still looks ok to me. > 2. Argument values are evaluated not from left to right.

If you have code that relies on that rule, I would agree it's brittle code and should be rewritten differently (perhaps by assigning to temporary variables explicitly).
