You'll have to propose an implementation strategy for that
which works without actually copying all the code, though.

But if _hidden were an attribute of the A instance that
you were trying to protect, it would succeed. So you
can't actually protect any direct attribute of a class
that can be subclassed. Which means we're back to the
situation of having to prevent access to class objects.
