Subject: Re: count symbols in a list From: Erik Naggum <firstname.lastname@example.org> Date: 02 Dec 2002 11:00:43 +0000 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Christophe Rhodes | No /feeling/ here, but at least the issue writeup of | MAPPING-DESTRUCTIVE-INTERACTION:EXPLICITLY-VAGUE disagrees with you; I do not see how mapping and list traversal are even remotely connected. | and the CLHS page on DOLIST does not seem to give a guarantee that | your view is the right one; in fact, it seems to go out of its way not | to: | dolist evaluates list-form, which should produce a list. It then | executes the body once for each element in the list, in the order in | which the tags and statements occur, with var bound to the | element. Then result-form is evaluated. tags label statements. This appears to be an argumentum ad ignorantiam. It does not say, from which you can legitimately conclude nothing. | I agree that normal practice is to expand into something that walks the | list once, but I think ANSI was careful not to mandate this; I do not see how you find evidence for this. | the downside of this absence of mandate is that you have to be slightly | more careful than you might otherwise want to be. Oh, Christ. So unroll the goddamn list, already. Instead of getting the point, that you can traverse a tree without resorting to recursion, we have this moronic quibble.
