Functions
constexpr tribool	make_tribool (int v) noexcept
	Explicit construction from some signed integer. <0 false, >0 true, 0 is other.
constexpr tribool	operator~ (tribool v) noexcept
	If tribool is true return false, if tribool is false return true, else return other.
constexpr tribool	operator& (tribool a, tribool b) noexcept
	If a is true and b is true, return true, if either is false return false, else return other.
constexpr tribool	operator| (tribool a, tribool b) noexcept
	If a is true or b is true, return true, if either is other return other, else return false.
constexpr bool	operator&& (tribool a, tribool b) noexcept
	If a is true and b is true, return true.
constexpr bool	operator|| (tribool a, tribool b) noexcept
	If a is true or b is true, return true.
constexpr bool	true_ (tribool a) noexcept
	Return true if tribool is true.
constexpr bool	false_ (tribool a) noexcept
	Return true if tribool is true.
constexpr bool	other (tribool a) noexcept
	Return true if tribool is other/indeterminate/unknown.
constexpr bool	indeterminate (tribool a) noexcept
	Return true if tribool is other/indeterminate/unknown.
constexpr bool	unknown (tribool a) noexcept
	Return true if tribool is other/indeterminate/unknown.
