tuple_element

 

template< std::size_t N, class Base, class... Tags > struct tuple_element<N, std::experimental::ranges::tagged<Base, Tags...>>   : std::tuple_element<N, Base> { };		(ranges TS)

The partial specialization of std::tuple_element for tagged provide compile-time access to the types of the tagged's elements, using tuple-like syntax. It simply forwards to std::tuple_element<N, Base>.
