Subject: Re: Q: tail-recursive procedure to generate all permutations of a list From: Erik Naggum <firstname.lastname@example.org> Date: 2000/10/06 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Bernhard Pfahringer | You're right that the suggested modification to your code is incorrect. | Sorry for that, this was not a deliberate insult, simply dumbness. | I thought I'd tested it, but obviously I was wrong. Anyway, no need | to go overboard, just a typical case of "don't assume malice, where | incompetence or ignorace suffices :-)" Well, I'd rather have malice any day over incompetence and ignorance used as excuses -- you can at least do something about the malice. ["Thank God children never mean well." -- Lily Tomlin] Your original code looks good, though. #:Erik -- If this is not what you expected, please alter your expectations.
