I've never bothered. Of course I'm also one of these people who routinely use AND and OR to return non-boolean values, which apparently a lot of people dislike (it's specifically contravened in Peter Norvig's style guide, for instance). BTW I prefer the trailing question mark convention over "-p". Scheme uses the question mark, but I'm not sure the convention originated there -- I think it may actually have started in the InterLisp community. Does anyone know? -- Scott _______________________________________________ pro mailing list pro@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/pro
