Subject: Re: Default package use list From: Erik Naggum <clerik@naggum.no> Date: 1998/03/13 Newsgroups: comp.lang.lisp Message-ID: <3098772282118179@naggum.no> * Marco Antoniotti -> Kent Pitman | If I understood well what you just said, in order to write, if not quite | "conforming", "maximally portable" code, it becomes imperative to know | with accuracy the 'default-package-use-list' used in the major CL | implementations. hm. I have taken a somewhat differing view. I always specify :USE to DEFPACKAGE and MAKE-PACKAGE, and so I know exactly what to expect. in particular, you can get seriously burned if the default package-use-list happens to make two different packages share a symbol and you try to use it for something useful in both packages. e.g., I had been irritated at the rule that I could not define anything of interest for symbols in the COMMON-LISP package for quite a while, and made a habit out of turning off the annoying package-lock warnings in Allegro CL (Unix). so I wrote a lot more code with this habit in place, and lo and behold, I used a name for a class that just happened to be in the COMMON-LISP package from two packages. thus came enlightenment. #:Erik -- God grant me serenity to accept the code I cannot change, courage to change the code I can, and wisdom to know the difference.
