It's fine to use virtual methods when you actually need runtime  
polymorphism at the same call site. The point is not to tie yourself  
in a knot if there really is true polymorphism, just to avoid paying  
runtime penalties for anything that can actually be a compile-time  
decision. If it can't be, then so be it.
