The most useful power of runtime polymorphism is based on invokving the right virtual functions through base pointers, so I don't see why it is bad to use polymorphism when it comes to destruction also. The way shared_ptr destroys objects is also polymorphic, it just doesn't use virtual functions. It's actually more powerful than virtual functions because it doesn't need a virtual function table; as illustrated, even a shared_ptr<void> can destroy the object correctly.

It does use virtual functions internally, just not virtual functions of the pointee. In Christ, Steven Watanabe
