I guess what you want to do is something like this:
```d
struct Broke
{
     double num;

     Broke opBinary(string op)(Broke rhs)
     if(op == "+")
     {
       return Broke(this.num + rhs.num);/*
       this.num += rhs.num;
       return this;//*option 2*/
     }

     Broke opBinary(string op)(double rhs)
     if(op == "+")
     {
       return Broke(this.num + rhs);/*
       this.num += rhs;
       return this;//*option 2*/
     }
}

void main()
{
     import std.stdio;

     Broke foo = Broke(5);
     Broke bar = Broke(15);
     bar = foo + bar;    // #1 bar == Broke(20)

     writeln(foo + 15);  // #2 print ok => 20
     writeln(foo + bar); // #3 print ok => 25
}
```
So you don't need to use alias. If you want it the other way 
(option 2), turn off option 1 then option 2 will open 
automatically. Thus, same Broke() gets values: 20, 35 and 55.
