22.10.11.4 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;

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).
