I am trying to translate the following C# code into D

    public class Test
       {
           public string Name;

           public static Test operator +(Test lvalue, Test rvalue)
           {
               if (lvalue == null) { lvalue = new Test(); lvalue.Name = "foo"; }
               if (rvalue == null) { rvalue = new Test(); rvalue.Name = "bar"; }

               Console.Write(lvalue.Name);
               Console.Write(rvalue.Name);

               return rvalue;
           }

       }

void main()
{
   Test T = null;
   Test B = null;
   T += B;
}

Whilst leaving the syntax of main() untouched.
