I'm not sure to understand why you want to do so - perhaps you could
tell more about your real use case ?

Anyway, and since it's not directly possible, a possible workaround
could be to pass a sequence of (key, value) tuples instead (possibly as
*args). This of course requires that you can modify the implementation
of myfunc().
