Subject: Re: loop & finally From: Erik Naggum <firstname.lastname@example.org> Date: 15 Sep 2002 06:58:58 +0000 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Software Scavenger | Both of those solve the problem in my example, but it was intended to be an | example of a more general problem. Both solutions were, I think, intended to solve the more general problem, but I now see that your major gripe is not the loss of features of `loop´, but consing up a brand new list, and this is a more valid concern in my view. The even more general problem than we solved would thus be a case such as (loop for code from 32 to 95 then from 160 to 255 do (... something with ISO 8-bit character set conventsions ...)) which would certainly be more convenient than, say, (loop for code from 32 to 255 unless (< 95 code 160) ...) So I am sympathetic to your request now that I understand your goal better. The `loop´ macro is normally supplied in source form with your Common Lisp implementation, so it should be possible to modify it locally, with all the drawbacks that has. I concur that some community effort to define such a mechanism would be useful, and it should be addable without serious compatibility problems because `then´ is not a valid clause. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
