Ah, thanks. But think about this one in Python:

  def f(a, b=10, *args, **keys):
    print a, b, args, keys

  f(1, b=2, c=4, d=8) # all right here

  # want to use b as keyword argument
  f(1, "a", "b", "c", b=2, c=4) # => ERROR

The problem arises, as it's undecidable if b is a keyword argument or
not, so that *args cannot be used in this case (or I am missing
something here).

Me, too :-)
