I believe object-orientation is dated

I don't know how many advances might be happening recently on some underground Smalltalk mailing-list, but in general, OOP has remained the same for decades.

Does everybody think it's good enough? Does nobody want new features that will make your code more expressive somehow? Watcha think?

OOP is not only about code reuse (I take it you're thinking about it?); it's also about modelling the real world problem in a coherent way inside a program.
