Ok: it is precisely when you change problem domains where one mechanism becomes superior to another.
If your point is that one mechanism is superior within a constrained domain, I have no problem with that. I was attempting to discuss the idea that the one mechanism might be universally better than the other. If introducing new problem domains is explicitly forbidden, then I have nothing useful to add. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
