I have no problem with ref const accepting rvalues.  As I understand it,  
Andrei's objection (and this may be wrong/incomplete) is that then there  
is no way to say you accept only lvalues as const ref and rvalues via  
non-ref (for performance reasons).  But I think there is no technical  
reason preventing that with D.
