As explained in Merchandise 39, for a traditional member functionality, the choice is in between allowing it to generally be called via a pointer to Foundation nonvirtually (but maybe with virtual behavior if it invokes Digital functions, such as in the NVI or Template Technique styles), almost, or not at all.
