Yeah, but you get bufferf pointers. As I hinted in my first post you can write a boilerplate around it, (with-temp-buffer (save-excursion (insert (mapconcat 'symbol-name '(c b a รก) "\n"))) (sort-subr nil 'forward-line 'end-of-line nil nil (lambda (a b) (funcall (if (fboundp 'string-collate-lessp) 'string-collate-lessp 'string-lessp) (buffer-substring (car a) (cdr a)) (buffer-substring (car b) (cdr b))))) (buffer-string)) But this seems like a lot of trouble just to get locale-aware sorting...
