I'd like to add another point worth mentioning. When I read the other poster's post, I was thinking about the semantics of OOP, specifically encapsulated objects and messages. I may have misinterpreted the other poster, but I hope it at least makes my other messages a bit clearer. (I think it's a little unwieldy to use Matrices that encapsulate its state for Linear Algebra, for example.)
