  A while ago I had to deal with that fact, that the optimizations 
that it does over several levels is often better than my own. 
Using shifts which obfuscates that I was actually doing a divide. 
I tried writing a unique array handler to shave a few operations 
and save time, only to get no real benefit from it.
