Subject: Re: Looking for a LISP function or macro ... From: Erik Naggum <firstname.lastname@example.org> Date: 1998/09/19 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Reini Urban <firstname.lastname@example.org> | but collect-if is also a good name. i just watched myself reading my | code with the unspoken words "keep if" so i named it like this. you, | erik, explained it the same way :) hm. I intended "keep" as a generalized term encompassing both "collect" and "retain", the point being that COLLECT would return a freshly consed list of elements collected from the argument list, while RETAIN would (destructively) delete the unwanted elements from the argument list. #:Erik -- ATTENTION, all abducting aliens! you DON'T need to RETURN them!
