Should out/ref parameters require the caller to specify out/ref like in C#?

I expect that we're going to see a DIP related to rvalue references at some
point here, because some of the folks (particularly the game folks) think
that it's critical to be able to have a function that doesn't care whether
it's taking a value by value or by ref - just that it takes it efficiently,
and they don't want to be forced to use auto ref to do it (since that
requires templates).
