Constructor taking a value properly convertible to the underlying type. U may be either an integral that can be converted to T without a loss, or another Checked instance whose representation may be in turn converted to T without a loss.
auto a = checked(42L); assert(a == 42); auto b = Checked!long(4242); // convert 4242 to long assert(b == 4242);
