That's the error that we've been using for (setq enable-multibyte-characters ...) since Emacs-21. > How about inventing a new error symbol for these cases? I haven't found a situation where I needed to distinguish those two error cases yet, so I don't see any need for that, but if you feel like it, that's fine (tho better make that new error be a sub-error of `setting-constant` so as not to break existing code).
