whoever writes code like that deserves to be punished.

I'd say this thread points to a misunderstanding of what keyword arguments
are, and how they should be used.  the basic rule is that you shouldn't mix and
match; use positional arguments for things that are documented to be positional
parameters, and keyword arguments for keyword parameters.  if you don't,
you'll end up with code that depends on implementation details.  and that's
never a good idea...
