    //!
    //! When creating a binary function object of type `Algo` whose signature
    //! is `Object x Object -> Return`, `nested_to<Algo>` can be used as a base
    //! class of `Algo`. Doing so will provide a static constexpr member called
    //! `to`, which has the following signature:
    //! @code
    //!     Object -> Object -> Return
    //! @endcode
    //!
    //! Note that the function object `Algo` must be default-constructible,
    //! since the algorithm will be called as `Algo{}(arguments...)`.
    //!
    //! @note
    //! This function object is especially useful because it takes care of
    //! avoiding ODR violations caused by the nested static constexpr member.
