Subject: Re: returning from a function (Ex: Re: some small proposed changes to standard) From: Erik Naggum <email@example.com> Date: 1999/07/25 Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * email@example.com (Christopher B. Browne) | I would suggest the connection that it may be *impossible* to create an | editor that *guarantees* that (for instance) an SGML document is valid at | every step. no, this is trivial to create. having such an "editor" would make design of DTDs almost doable, since the "editor" would have to create a complete document for you and then let the user make branch decisions, showing which options were available at all times. (what's not so trivial is making such an "editor" comfortable to use for humans.) #:Erik -- suppose we blasted all politicians into space. would the SETI project find even one of them?
