In a recent interview in IEEE Software (or was it Computer?), Barne
Stroustrup cited as an advantage the fact that C++ supports multiple
programming paradigms. I agree with him.
The argument that "pure OO" is better is a vestige of our unbridled
enthusiam for all things object-oriented in the 80's. Arguments like
this are just religion - what I call the Argument By Appeal to Higher
What these people forget is that systems (both natural and artificial)
are constructed using a variety of techniques. Nature doesn't care
about purity, only dogmatic programming language designers do. Mother
Nature, and organizations that fund development of software systems,
only care about what works.
