  Maybe a very simple change/addition; Like perhaps @ref? 
(Attribute ref, Alternate ref, auto ref.. All sorta fit for it's 
meaning).

  So...

  void func1(ref int x);  //D lvalue-only ref
  void func2(@ref int x); //works like c++'s ref

  Seems fairly easy to tell apart, and still leaves const-ness as 
an option.
