# exotic-crtp

**Article :** [Rethinking Static Polymorphism with C++23](https://medium.com/@felixolivierdumas/exotic-crtp-rethinking-static-polymorphism-with-c-23-89f9e75e8ffd)

## The pattern

```cpp

namespace exotic {

    template

    struct crtp_access : From... {};

    template

    constexpr decltype(auto) as_crtp(T&& obj) noexcept {

        using crtp_access_t = crtp_access>;

        return static_cast(obj);

    }

}

struct Base {

    void interface(this auto&& self) {

        return as_crtp(self).implementation();

    }

};

struct Derived : Base {

    void implementation(this crtp_access self) {

        std::cout << "Derived implementation" << std::endl;

    }

};

```
