   I thought the answer to this one was easy, but maybe I'm missing   
   something?   
      
   Given that an rvalue can be implicitly created from an lvalue, I   
   would venture to guess that the rvalue-qualified version would be   
   useful for both --- the compiler would just create an rvalue from   
   the given lvalue (or just "pretend" to create;  or actually create   
   it but then have the optimizer optimize it away).   
      
   Am I missing something?
