Could be useful, sometimes. But why would one write a mathematical class that then uses default addtion?
One wouldn't. One *might* write a class that makes assumption about the RHS (like, for example, that you can just yank out the integer value) but that'd be sub-optimal.
I think MMD is the way to go, so I'm working on the scheme to install MMD methods for vtable functions. And yeah, I'm re-evaluating dispatch to these things too. I'd like to avoid the round-trip through C if we can, since bytecode vtable functions may end up being popular. (And there's that whole dispatch-messes-up-DOD thing...)
