Re: Generic operator overloading for immutable types?

In the following code is there any way to make the `opBinary` method generic to be able to accept immutable as well as a standard type? The code currently passes the unit test but I wonder if I could get rid of the duplication to overload the operator? I'm failing badly.

        public inout(Rational) opBinary(string op)(inout(Rational) rhs) inout {
          static if (op == "+") {
            return Rational(0, 0);
          } else {
            static assert(0, "Operator '" ~ op ~ "' not implemented");
          }
        }
