Defined in header <experimental/ranges/utility>
template< TagSpecifier Tag1, TagSpecifier Tag2, class T1, class T2> constexpr ranges::tagged</*see below*/, Tag1, Tag2> make_tagged_pair(T1&& x, T2&& y);		(ranges TS)

Convenience function for creating a tagged pair, deducing the element types from the arguments (the tag specifiers must be explicitly specified).

The see below portion of the return type is decltype(std::make_pair(std::forward<T1>(x), std::forward<T2>(y))).

Return value

R(std::forward<T1>(x), std::forward<T2>(y)), where R is the return type.
