It is a valid point that you can simulate interfaces with inner classes / record components. But you can also write object oriented code in raw C (see GNOME), it's rather the decision which constructs to make first class citizens of a given language. Your paper also shows that interfaces should not be hard to implement in compilers. Right? Thank you, Wojtek
