A.d:
----
import B;

class Foo {
public:
    void call(Bar b) {
        void delegate(int) dg = &b.test;
        dg(42);
    }
}

void main() {
    Bar b = new Bar();
    Foo f = new Foo();
    f.call(b);
}
----

B.d:
----
import std.stdio;

class Bar {
private:
    void test(int id) {
        writeln("Bar called with ", id);
    }
}
----

Output: Bar called with 42
But should be rejected.

Reduced a little bit:

-----
module a;
import b;

void main()
{
    auto s = S();
    auto f = &s.f;  // no error
    f();  // no error

    auto sf = &S.sf;  // error
}
-----

-----
module b;
struct S
{
    private void f() { }
    private static void sf() { }
}
-----

I'm unsure, but maybe we should also classify this as major because it breaks
the protection?
