What if auto_ptr<T> had one more level of indirection, that is,
instead of having

T* ptr;

had

T** ptr;

so that it could change *ptr even if the auto_ptr were const?

This new pointer should be allocated and de-allocated by the auto_ptr
class. Some care would have to be taken to assure this other pointer
would always be deleted.

Maybe the auto_ptr template could also add a new parameter to allow
the definition of a specialized allocator for those pointers.
