Yes but I neglected the lvalue/rvalue issue. In some cases the code 
won't compile if the return type of the newly written explicit function 
is not 'ref'. For example, the 'ref' below is essential for the 
following use case:

class C {
     int* result;

     // HERE
     ref asIntPtr() {
         return result;
     }
}

auto main() {
     auto c = new C();

     int i;
     c.asIntPtr = &i;
     assert(c.result == &i);
}
