No disagreement here... I was just noting that data and behaviour are
largely separated only in the way you interpret things.

Yep. I tend to look at it as defining interfaces vs defining
implementations. You reuse interfaces and throw away implementations
in most systems I've seen.

The problem we face is that it's hard to decide upon an interface
until you are aware of the implementation constraints... and that
interfaces often need to evolve over time.
