I wouldn't go with tie (if it even works?). I'd overload = to automatically clone the object on assignment.

Another approach is to use immutable objects. Such a class wouldn't provide a method for incrementing the object; it would provide a method that returns a new object with the higher value.

Both of these approaches add the unnecessary computational and memory overhead of creating clones in situations where they aren't needed.
