Why is evaluation more intelligent than search?  If you have a program with a
very simple search, that spends a large percentage of its time in evaluation,
and you make the search more clever, so that a higher percentage of the time is
spent in search, did the program become dumber?

And what about programs that do incremental evaluation?  A good incremental
evaluation should produce the same results as the same evaluation carried out at
the tips, and it should do it more quickly.  Is this program dumber?

I think that one of the greatest wastes of time is trying to assign categories
to these programs.
