See below for words of wisdom regarding loop and macros. I have seen that mentioned before.

I like the idea of macrolet. And I will remember the (progn ...) trick as well.
Which reminds me to mention that LOOP shouldn't be used in the expansion of macros because of this kind of problems... When writting macros, it's safer to use DO, DO*, DOLIST, DOTIMES or even TAGBODY/GO in the expansion.

Oooh, thanks. I have seen that mentioned before, but I will now *pay attention* to it.
