To add to Lasconic's comment, an overriden virtual function in a subclass
gets called regardless of whether the class is referenced by its base class
or derived class. But an overloaded function of the same name only gets
called if you reference the subclass. Thus, there is a potential for
unexpected results if you reference the instance by its base class.
