int is immutable, so I expect the int part of MyInt to be immutable.
If you want a mutable int, don't inherit but compose/delegate (I'm
not familiar with the terminology).
You can't replace the base object when inheriting from regular classes
either. For regular classes there is even no base object (the same
__dict__ is used).
