Ok, I think we are in agreement. Now, someone should warn me about the rule against mixing metaphors ;)

Brian,

I agree with your point about losing detail when painting with a
large brush. At the same time, I would wager that is why he said "in
virtually all cases".

In boxing it is considered a bad idea to let yourself get backed into
the ropes. Ali did so with great success against Foreman, but it is
still a bad idea in general.

So it is, I think, with evaluate(). It is usually not a good idea.
Certainly there will be cases where it is a good idea.

The performance issue, however, isn't a major one. You can usually
get more impact on perceived performance with image compression than
any single syntax adjustment.
