概要 

namespace std { namespace experimental { namespace ranges { inline namespace v1 {
template <TaggedType... Types>
using tagged_tuple = tagged<tuple</* TAGELEM */(Types)...>,
                            /* TAGSPEC */(Types)...>;
template <TagSpecifier... Tags, class... Types>
  requires sizeof...(Tags) == sizeof...(Types)
    constexpr /* 查看定义 */ make_tagged_tuple(Types&&... t);
}}}}
