Could you?  Maybe I'm having a blind spot, but, without having a
custom metaclass (redefining __getattribute__ differently from the
implementation in object), how would you do it?  I.e. how would you
code a type instanceproperty such that:


class UIP(object):

    def getfullname(self): return 'Monty Python'

    def __init__(self):
        self.fulname = instanceproperty(self.getfullname)

x = UIP()
print x.fullname


would result in x.getfullname() being _called_?  I just can't
see how, and I'd like to learn -- thanks!
