order dependent

New Comment:
@johannes: How could you then hint that a class must be Traversable in some way
(either Iterator or Aggregate)? Or shouldn't that be possible at all?

Actually we should forbid extending Traversable. This should only only only be
used by internal classes (Iterator, iteratorAggregate or classes providing the
C get_iterator hooks)

Description:
------------
When implementing an interface which extends Traversable together with one of
the concrete Traversable implementations (i.e. Iterator or IteratorAggregate)
the latter must be named first in order to not throw an error.
