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.

I think you are painting with a pretty broad brush here. I think the
point is that it is preferable to avoid, but actually has its
limited uses. I also think that saying that "it demonstrates a lack
of understanding of the features of the language " is mistaken as
well. The use of evaluate alone does not, in fact, demonstrate
this...and by coloring everything black and white you lose alot of
detail. I cannot think of a programming rule to which there doesn't
exist exceptions, and the reasoning that has been offered thus far
does not lead to such grandiose assertions. I am, by the way, saying
this as someone who has managed to avoid evaluate ;)

Subject: Re: [CFCDev] CFINVOKE vs. Evaluate
The point is that in virtually all cases:
1. evaluate() is slower
2. there is no reason to use it
3. it is more difficult to read and understand
4. it demonstrates a lack of understanding of the features of the language
