// Previously, when we call a no-diff function side a differntiable function, we will have to use no_diff to tell compiler that this is intended.
// However, if the parameter is just a constant, there is no need to use no_diff, because constant won't carry any derivative information.
// Therefore, this test is to check we won't report any error when the parameter is a constant in this case.
