Idon't have any intuition that "virtual.lower" would return a functionthat calls the "lower" attribute instead of returning a function thatsimply accesses that attribute.If we're going to move away from the itemgetter() and attrgetter()style, then we should be consistent about it and provide a solution(or solutions) that answers all of these problems:    obj.attr    obj.attr(*args, **kwargs)    obj[key]I'm not sure that there is a clean/obvious way to do this.STeVe-- You can wordify anything if you just verb it.        --- Bucky Katt, Get Fuzzy
