ok, i need the traverse_using(), the iterate_depth_first (which i can
do myself as u said so its not really needed), and the pre-traverse
name[6:] filtering:
visitors = dict( (name[6:], getattr(self, name))
for name in dir(self)
if name.startswith('visit_') )
u have this filtering copied twice, i guess it has to be in one place.
so the actual traverse-call has to be one more method.. to be easy
replaceable.
that should make a good clean interface.
