During this scarce scenario, you could potentially make the destructor public and nonvirtual but Plainly document that even further-derived objects will have to not be utilised polymorphically as B’s. This really is what was done with std::unary_function.
Discussion – references to extra considerable rationale and/or illustrations positioned outside the main lists of procedures
