Very Very true :-)
Too often, people slip from "anything can be done with classes" to "anything must  be done with classes".

I'm always amazed by people who value "pure OO" language. It's like having just one tool in one's tool box, and being proud of it.

Everything can be done with a swiss army knife, so everything must be done with a swiss army knife. You don't need that ol' chain
saw any more. Want to cut a big tree ? all you need is a swiss army knife (and patience).
