I guess I'm just a lazy slug. I usually go with $a, $b, $c, etc. Years of schooling in Basic, Fortran and C taught me that for loops always need to be $i, $j, $k and that if you need more than four levels of loop you should start over...

Of course, in perl that bites me on the ass at "m" or "s" or "x" or "y".
