Thank you, it is much clearer now!

So, I'll have to rework my code to see where I can put ps:ps and where
ps:ps*, because I'd prefer most of the code macro-expanded at compile
time. I'm going currentyl through several lisp books, and I have
decided to leave the onlisp for later when I get an better grasp on
things, because when I first started with it, it became too advanced
very fast for one that had no previous experience with lisp.
