I've been trying for two weeks now to get this message through.
This is the fifth attempt; maybe this route to SU-AI will work.

I think it would be great if a Common Lisp version of PSL's FOR macro were
written and submitted to the Yellow Pages. I also think it would be great
if there were a Yellow Pages at all!
I personally would never use this macro if I had an alternative, primarily
because of the fixed order of evaluation, which means that you can write code
that looks like it will be evaluated in a certain order, but actually it
will be evaluated in a different order, causing subtle bugs. I also find the
syntax less readable than the syntax of LOOP, but that of course is more a
matter of personal taste than of anything that a group could agree on.
