Defined in header <tuple>
template< class... Ts, class... Us >     requires requires { typename std::tuple<std::common_type_t<Ts, Us>...>; } struct common_type<std::tuple<Ts...>, std::tuple<Us...>>;		(since C++23)

The common type of two tuples is a tuple consists of the common types of all corresponding element type pairs of both tuples.

The common reference type is defined only if both tuples have the same number of elements, and their all corresponding element type pairs have common types.
