Could someone point out how do that/what's wrong with my attempy?

+ is overloaded with opBinary, and += is overloaded using opOpAssign:

Soon as I posted I found out opOpAssign.
I've had got close than I thought:

        List opOpAssign(string op)(int rhs) if(op == "+")
        {
                items ~= rhs;
                return this;
        }

Thanks!
