Obfuscation? Are you saying that just because you wrote this code?  So
what is the usage of a macro? I think you are having a defensive
position here.

The macro is self-explanatory, ARRAY_SIZE, so the macro gives you the
*size* of the array. You don't need to know how that is done, if you
want, just go to the declaration of the macro.
