It's mostly intended so that someone can use a dynamically scoped variable without worrying about stepping on other people's toes, yes. > In that case, should desktop-first-buffer, desktop-buffer-ok-count, and > desktop-buffer-fail-count be given init values to prevent local specialness, > so that code outside desktop.el that calls desktop functions that use those > variables doesn't have to do defvar on them? We could, but AFAICT, these vars are only used in desktop.el (they could/should use a double-dash to indicate that they're internal), so it would be kind of pointless. Stefan
