In 3.x, you would write __setitem__ to recognize that the 'key' is a 
slice object rather than an int and act accordingly. (In 2.x, you would 
write __setslice__.) Actually, if you write

def __setitem__(self, key, value):
   self.somelist[key] = value

as you might have done already, you get slice getting, setting, and 
deleting for free. Try Dave's line in your code.
