        ~Foo() { std::cout << "~Foo...\n"; }
    };

    struct D
    {
        void bar() { std::cout << "Call deleter D::bar()...\n"; }
        void operator()(Foo* p) const
        {
            std::cout << "Call delete for Foo object...\n";
            delete p;
        }
    };

    int main()
    {
        std::unique_ptr<Foo, D> up(new Foo(), D());
