Try next code:

import std.stdio;

template TX(T)
{
struct A
{
    T x;
    T y;

    public void opOpAssign(string op)(double d)
    {
            debug writeln(op);
            if (op == "+")// +=
            {
                x += cast(T)d;
                y += cast(T)d;
            } else

            if (op == "-") // -=
            {
                x -= cast(T)d;
                y -= cast(T)d;
            } else
            if (op == "*") // *=
            {
                x *= cast(T)d;
                y *= cast(T)d; 
            } else
            if (op == "/") // /=
            {
                x /= cast(T)d;
                y /= cast(T)d; 
            } else 
            if (op == "%") // %=
            {
                x %= cast(T)d;
                y %= cast(T)d; 
            }
        }
    }
}
void main(string[] args)
{
       TX!(double).A a;
    a.x =10;
    a.y = 10;    
    a%=8.0;
    writeln(a.x, " ", a.y);    
}

You'll see that the a.x won't change. It must be 2 after %= operation.

Thank you.
