201/// @brief Re-implementation of C++17's index_sequence and the helper alias
202/// make_index_sequence. This was introduced to fix an issue with clang's
203/// builtin implementation which treats template specializations of builtin
204/// templates differently when a subsequent parameter is dependent. The
205/// result is a resolution failure during partial specialization selection.
206/// For example, the following will fail to specialize:
207///
208/// @code
209/// struct Test { static const int VALUE = 1; };
210///
211/// template <typename T, typename S = std::make_index_sequence<T::VALUE>>

214/// template <typename T> struct Adapter<Item<T>> {}; // FAIL: will never be selected.
