NAME
std::tuple_size<std::experimental::ranges::tagged> - std::tuple_size<std::experimental::ranges::tagged>
Synopsis
template< class Base, class... Tags >
struct tuple_size<std::experimental::ranges::tagged<Base, Tags...>> (ranges TS)
: std::tuple_size<Base> { };
The partial specialization of std::tuple_size for tagged provides the ability to obtain the number of elements in a tagged object using tuple-like syntax. It simply forwards to std::tuple_size<Base>.
