Oh bullshit, Mr. Rubin. As usual, you are wanting PL/I++++, not C. And
a compiler that reads programmer's minds. If you really don't want to
do the division, maintain integer indexes, not pointers.

If you think that pointer manipulation is going to give you the
better code, use them. If you think that index manipulation is going
to give you the better code, use those. And if you can't figure which
is better, how, pray tell, do you figure the compiler will figure it
out? C at least gives yo a fighting chance by giving you a choice.
