I don't know why 'T2' was in output, it should be 'T' (and it is now).

As for why it works: this is used to pick a specific override in some base
class, e.g.:

class A
{
    void test() { }
}

class B : A
{
    override void test() { }
}

class C : B
{
    override void test() { A.test(); }
}

If you use 'super.test()' you would end up calling B.test instead of A.test.
