For some purposes, auto ref does the wrong thing. Whether you get 
a reference depends on whether you pass an lvalue or an rvalue. 
But some templates need to take either a struct by reference, or 
a class/interface (already being a reference) by value.

This is the case deadalnix mentioned further up in this thread. I 
don't know whether it applies to Manu's code, too. AFAIUI he's 
more concerned about forwarding parameters in wrapper types.
