Yeps, true. Another solution would be to add a __getitem__ method 
pointing to the same implementation, ie:

     __getitem__ = __getattr__

Most of the times, in a situation such as the one described by the OP, 
one knows by advance if a given LDAP attribute will be used as 
monovalued or multivalued. Well, this is at least my own experience...
