Requiring arguments to be passed as keyword arguments

[Scott.David.Daniels]

What about the fairly obvious:
      def fun(...positional..., none=None, ...keyworded...):
         if None != none: raise ArgError, "Args to fun must be keyword
args"
         # ...

It is not beautiful but it is short, clear and succinct
