The _entire_ reason that auto ref was introduced in the first place was to 
solve the const ref problem. That's what it's for. It wouldn't exist otherwise. So,
it's completely relevant to any discussion of const ref.

However, Walter misunderstood what Andrei meant by the feature, so it only got
implemented for templates, and given how Walter implemented it, it _can't_ be
implemented with non-templated functions. But it could be implemented with slightly
different semantics such that it solves the const ref problem as orignally intended.
It's just that it would then have slightly different semantics between templated
and non-templated functions.
