friend constexpr basic_vec& operator+=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator-=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator*=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator/=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator%=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator&=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator|=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator^=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator<<=(basic_vec& lhs, const basic_vec& rhs) noexcept;
friend constexpr basic_vec& operator>>=(basic_vec& lhs, const basic_vec& rhs) noexcept;

Let op be the operator.

Constraints: requires (value_type a, value_type b) { a op b; } is true.

Effects: These operators apply the indicated operator to lhs and rhs as an element-wise operation.

Returns: lhs.

friend constexpr basic_vec& operator<<=(basic_vec& lhs, simd-size-type n) noexcept;
friend constexpr basic_vec& operator>>=(basic_vec& lhs, simd-size-type n) noexcept;

Let op be the operator.

Constraints: requires (value_type a, simd-size-type b) { a op b; } is true.

Effects: Equivalent to: return operator op (lhs, basic_vec(n));
