Following the rule used for argument processing now, if it's unambiguous,
it should be allowed, and not otherwise.  So, IMHO, the above two should
be allowed, and I suspect 

  Foo.__init__(self, *args, *args2)

could be too, but

  Foo.__init__(self, **kw, **kw2)

should not, as dictionary addition is not allowed.

However, I could live with the more restricted version as well.
