+** Extend ~add-to-list~
+:PROPERTIES:

+:END:
+One function I find missing regarding ~add-to-list~ is ~add-all-to-list~
+so I can add multiple elements to a list at once. Instead, with
+vanilla Emacs, I have to repeatedly call ~add-to-list~. That’s not very
+clean. Let’s declare this missing function:
+#+begin_src emacs-lisp
+(defun add-all-to-list (list-var elements &optional append compare-fn)
+  "Add ELEMENTS to the value of LIST-VAR if it isn’t there yet.
+
+ELEMENTS is a list of values. For documentation on the variables
+APPEND and COMPARE-FN, see `add-to-list'."
+  (let (return)
+    (dolist (elt elements return)
+      (setq return (add-to-list list-var elt append compare-fn)))))
