Trivial fix of sample code:
----
struct Foo
{
    int x;

    ref Foo opOpAssign(string op)(ref Foo f) if(op == "+")  // <- "+="
    {
        x += f.x;
        return this;
    }
}
void main()
{
    Foo f1 = Foo(1);
    Foo f2 = Foo(2);
    f2 += f1;
}
----

And, on dmd 2.054 (d36b3b12fc4814e59f3a0d680b8700e787b1ceff) this code has
passed to compile.
