Or am I just confused and haven't read the manual? yes, you are seriously confused and you spread lies and confusion to others, as well. what you're doing should be illegal. it may well be.

I sincerely think you should stop doing something that clearly creates so many problems for yourself. instead of being fun and profitable, Common Lisp is hurtful to you. go do something else and make yourself happy. #:Erik
