> Inheritance isn't the root of all evil, dynamic dispatch is. It's a remarkably powerful implementation detail but one with enormous cost ...

This is not an "enormous cost" by any reasonable definition. 0 - https://en.wikipedia.org/wiki/Virtual_method_table https://en.wikipedia.org/wiki/Virtual_method_table
