Could you give a small example, perhaps I don't understand. with a
declaration (using an extended version of C):

     int x(5:49),y(0:44);
     int i,k;
     i=6;
     k=x(i);        /* easy to write access to second item */
     k=y(i-5);      /* more trouble to write access to second item */

However, with a reasonable compiler, both assignments to k will generate
identical code.  Your compiler may vary :-).  But if you are writing time
critical code with a faulty compiler, I guess you do what you can.
