So what? It just must work. Efficiency of a particular operation doesn't mean efficiency of a program: it can use lvalues most of time. > D's solution is to use auto ref, but I think your attempts to use it show > that it doesn't work. You should file a bug with your program 3. auto ref works only for return values, implementing it for parameters means combinatorial bloat.
