Now, can the code that is created depend upon The truth that A.C is usually a compile-time constant? I.e., can the usage of A.C simply just be replaced by the value 0? In the event you say "Indeed" to this, then that means which the developer of the are not able to change the way that A.C is initialized -- this ties the hands of the developer of A devoid of permission.
