I think it's needlessly narrows the scope of the problem.
Consider this code:

#include <stdio.h>

#define hide_size_of_var sizeof

int main(void) {
     int a[hide_size_of_var(int)];
     int i;

     for (i = 0; i < hide_size_of_var(int); i++) {
         a[i] = i*3;
         printf("i: %d a[i]: %d\n", i, a[i]);
     }

     return 0;
}

It compiles just fine in a C compiler and runs from 0 to 3 as expected.
GCC 4.8.2 doesn't say anything about it with -Wall.

I think you should pass everything through as is inside the '[' and ']' and
let the C compiler fail if the code is not valid.
