+1. It's a pretty common pattern for handling optional keyword
arguments, e.g. in subclass methods.
class Foo(Bar):
def foo(self, *args **kws):
mine = kws.pop('mine', None)
super().foo(self, *args, **kws)
do_something_myself(mine)
Now the question is, what guarantees does the language make about the
ordering of kws that Foo.foo() is passing to Bar.foo()?
