Oops--thanks for pointing that out. I sometimes wonder, however, why
it was set up this way. Except for speed concerns, I see no reason
why, if we set up the algorithm a different way, it couldn't search
from right to left. A simple approach would be like this:
def findattr(obj, name):
while (obj is not None):
base = getattr(obj, 'aq_base', obj)
if hasattr(base, name):
return getattr(obj, name)
obj = getattr(obj, 'aq_parent', None)
raise AttributeError, name

Of course, Jim would probably look at my example and want to hit me.
He likes things to be optimized. :-)
