This is indeed a source of errors in C nested loops. Say we have
these macros:

   FOR (i, 0, N-1)
     FOR (j, 0, i)
       ...

we are less likely to make some copy paste error like
 
   for (i = 0; i < N; i++)
     for (j = 0; j < i; i++)
       ...

Int he past, I've run into bugs in nested loops, along these lines.

In loop-heavy code, making a macro like the FOR above might not
be a bad idea.
