Functions
template<class To , class From >
constexpr bool	kamping::in_range (From value) noexcept
	Checks if an integer value can be safely casted into an integer type To, that is, it lies in the range [min(To), max(To)].
template<class To , class From >
constexpr To	kamping::asserting_cast (From value) KAMPING_NOEXCEPT
	Casts an integer value to the integer type To. If the value is outside To's range, throws an assertion.
template<class To , class From >
constexpr To	kamping::throwing_cast (From value)
