Of course, this obvious solution has a problem: a programmer can't easily sub-class Int.

I can't see that subclassing int is a particularly useful thing to do, even as matters stand today. As soon as you do any operation on your int subclass, you get a result which is not an instance of your subclass any more, which makes using it rather fragile.

Does anyone have a real-life use case for subclassing int?
