If I look in my Common Lisp directory, I have 94 occurences of `loop' there. Various complex things. But I try not to over load things. The `cl' library is now in "obsolete" directory and function `cl-loop' is not obsolete. So I guess maybe you will not need `require', it should work, it is now in `cl-macs.el' file. Package describes it as extensions to Emacs Lisp for compatibility reasons. Same with `while': (let ((list '((1 2) (3 4) (5 6)))) (while list (let* ((pair (pop list)) (x (car pair)) (y (cadr pair))) (message "%d + %d = %d" x y (+ x y))))) I would like above rather than this one below, as I don't seek CL compatibility: (cl-loop for (x y) in '((1 2) (3 4) (5 6)) do (message "%d + %d = %d" x y (+ x y))) Or with `mapc': (mapc (lambda (pair) (let ((x (car pair)) (y (cadr pair))) (message "%d + %d = %d" x y (+ x y)))) '((1 2) (3 4) (5 6))) And then benchmark: (benchmark 100000000 (let ((list '((1 2) (3 4) (5 6)))) (while list (let* ((pair (pop list)) (x (car pair)) (y (cadr pair))) (message "%d + %d = %d" x y (+ x y)))))) ⇒ "Elapsed time: 5.520809s" (benchmark 100000000 (cl-loop for (x y) in '((1 2) (3 4) (5 6)) do (message "%d + %d = %d" x y (+ x y)))) ⇒ "Elapsed time: 5.784922s" (benchmark 100000000 (let () (mapc (lambda (pair) (let ((x (car pair)) (y (cadr pair))) (message "%d + %d = %d" x y (+ x y)))) '((1 2) (3 4) (5 6))) nil)) ⇒ "Elapsed time: 5.158536s" I thint that benchmark says nothing much, the tests are vague and they are about as fast. `while' is probably slowest. `while' is giving me more clarity. Yet your example still did not replace this function below, there are no list of lists inside: (defun outline-highlight-keywords () (interactive) (let ((my-keywords '("TODO" hi-yellow "DONE" hi-green "URGENT" hi-red-b))) (while my-keywords (let ((keyword (pop my-keywords)) (highlight (pop my-keywords))) (highlight-regexp keyword highlight))))) -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
