Yeah, as with everything, I guess languages need balance. In the case of Modelica (and others inspired by it), we can have functions that are not part of any class at all. So, you could just have a function called evalCollision that accepts two instances of the class BilliardBall and calculate the net result. My main point, though, was that these new languages are way better than Simulink etc. that went before them.
