I think that just an out-dated way of looking at things. I expect Hal
would agree that needs to be updated to current trends.

I remember once, Hal and I got in a big argument about floating-point
arithmetic. A tad spiteful I pointed out a flaw in his book. Despite
the heated argument, he took it quite gracefully, saying he was always
happy to receive comments/corrections. That was pretty damn
respectable, IMHO. If he doesn't see this thread, write him directly.
