It's an int _subclass_ so that it is no bigger than an int.
If you use __slots__ to eliminate the overhead of an instance dict, you'll get an object consisting of a header plus one reference, which is probably about the size of an int. But you'll also need an int to put in that slot, so the total size will be about twice that of an int. Another approach would be to subclass array.array and give instances of it type integer and size 1. Together with empty __slots__, it will probably be a bit bigger than an int, but it might still be smaller than a custom object plus an int. If all of these are still too big, you might need to find some way of packing multiple instances into a single array.array. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
