As far as I understand the "usability disaster" of disallowing rvalue
references is that I have to define a non-ref overload forwarding to my
function(ref arg).
That ref can't be for functionality, because I'm expecting references to
rvalues/temporaries. => ref is merely for performance, and the parameter
can be const.
Now, this may be too naive, but what about allowing the compiler to pass
regular (not declared ref) const arguments per reference as it sees fit?
It would be just another optimization.
I'd declare function(const arg) and that would be it.
Aliasing would kill that. We considered it.
