If your intent is to force derived classes to override a method, and
you want to give a compile error when attempting to call this function
if the derived class did not, we already have a mechanism for that:
pure virtual functions.

If that won't solve the issue, you should explain what functionality
pure virtual functions lack that you're looking for.
