Here is a start:
>>> class mlist(list):
def __init__(self,it):
list.__init__(self,it)
self.maxlen = len(self)
>>> ll = mlist((1,2,3))
>>> ll.maxlen
3
Now, add methods for the list grow methods (.append, .extend, and
.__setslice__) which follow a call to the parent method with
self.maxlen = max(self.maxlen, len(self)) # or equivalent code
