Let's not forget that the "sub-programs" which perform acceptably today
for occasional interactive use are often the buggers that chew up our
day-end window when called repeatedly in large batch runs!

My point is that a good programmer should be looking forward a little
ways at anticipated uses, and not just at the immediate problem at hand.

Of course, I know I'm preaching to the choir in your case. My comments
are not directed at you, but at the group in general.
