/// ===============
/// 
/// How to unpack a sequence can be defined by specializing `unpack_sequence`.
/// By default, `std::tuple` is already specialized.

/// Synopsis
/// --------

///     template<class Sequence, class=void>
///     struct unpack_sequence;
/// 
/// Example
/// -------
/// 
///     #include <fit.hpp>
///     #include <cassert>
/// 
///     template<class... Ts>
///     struct my_sequence;
/// 
///     namespace fit {
///         template<class... Ts>
///         struct unpack_sequence<my_sequence<Ts...>>
///         {
///             template<class F, class Sequence>
///             constexpr static auto apply(F&& f, Sequence&& s) FIT_RETURNS
///             (
