Anyone out there?
Criticism about the objective of my question, not just the execution,
gratefully received!
Basically, if I have a
class This:
def __init__(self, x, y):
self.x=x
self.y=y
self.data = {}
and then make all my setitem and getitem calls refer to self.data; is it
sensible and right to be able to refer to self.data[n]?
