Functions, unlike methods, do not work with rvalues.

Ie

   struct S {
      long[999999] data;
      auto f() { return data[0]; }
   }

   auto g(ref S _this) { with (_this) return data[1]; }

   void main() {
      auto a = S().f();
      auto b = S().g();
   }

Shouldn't this be possible if you want to make g a template 
function and use auto ref? Regardless, it doesn't. Probably a 
compiler bug:

  struct S {
     long[999999] data;
     auto f() { return data[0]; }
  }

  //No good
  //auto g(T: S)(auto ref T _this) { with (_this) return data[1]; 
}

  //Doesn't work either
  //auto g()(auto ref S _this) { with (_this) return data[1]; }

  void main() {
     auto a = S().f();
     auto b = S().g();
  }
