AFAIK, if you have an overload that varies solely on ref, then rvalues 
go to the non-ref and lvalues go to the ref. If this is not the case, 
it's *intended* to be the case, and should be filed as a bug.

auto ref just templates that. And in your case, it's actually clearer 
and cleaner not to use auto ref.

Not sure if this answers your question, or if it turns out to be a 
viable solution.
