Operator Overloading with multiple return types

[eXodiquas via Digitalmars-d-learn]

Hi everyone,

i'm currently working on a small physics engine and I thought it 
would be a nice feature to overload the operators of my vector 
struct so I don't have to make ugly function calls just to add 
and "multiply" my vectors. The problem now is that overloading 
the addition and subtraction of my vector struct is straight 
forward because both return and take a vector, dot product is not 
working for me because it is not possible to overload a function 
by return type (at least not that I am aware of).

My code looks like the one from the dlang docs:

Vector opBinary(string op)(Vector rhs)
{
    static if (op == "+") return Vector(this.x + rhs.x, this.y + 
rhs.y);
    else static if (op == "-") return Vector(this.x - rhs.x, 
this.y - rhs.y);
}

As you can see for the dot product the return type has to be a 
float/double and not a vector. Is there any way to achive this 
behaivour with D2? The opMul() function is not D2 style and I 
don't want to use it.

Thank you very much,
