23.14.9.3 Class template bit_­xor [bitwise.operations.xor]

template<class T = void> struct bit_xor { constexpr T operator()(const T& x, const T& y) const; };
constexpr T operator()(const T& x, const T& y) const;
Returns: x ^ y.
template<> struct bit_xor<void> { template<class T, class U> constexpr auto operator()(T&& t, U&& u) const -> decltype(std::forward<T>(t) ^ std::forward<U>(u)); using is_transparent = unspecified; }; template<class T, class U> constexpr auto operator()(T&& t, U&& u) const -> decltype(std::forward<T>(t) ^ std::forward<U>(u));
Returns: std​::​forward<T>(t) ^ std​::​forward<U>(u).
