--- Comment #1 from naydef <naydef at abv.bg> ---
Adding 'static' to class Delegate does not change anything(suggested by Adam)

-------------------------------------------------
auto HookVFunc(T)(T)
{
    extern(C++) static class Delegate
    {
        void dd() {}
    }
}


class SamplePlugin
{
    void Load()
    {
        HookVFunc(&GameFrame);
    }

    void GameFrame()
    {
    }
}
