struct S {
    int a;
    void fun() {
        this.a = 1;
    }
}

void main() {
    auto fp = &S.fun;
    fp();
}

Outputs:
object.Error: Access Violation


The solution is either to delegalize it or (better) include the hidden
parameter into the function pointer signature. So that &S.fun would be of type
void function(ref S).
