According to the specs of the new operator overloading this program is correct,
but it currently doesn't compile:


struct Foo {
    int x;
    Foo opUnary(string op:"++")() {
        this.x++;
        return this;
    }
}
void main() {
    Foo f = Foo(5);
    f++; // line 10
}


The compiler gives:
test.d(10): Error: var has no effect in expression (__tmp1)
