I want to be able to get all matching elements from an alist (thinking about extending imenu). Something like (assoc-all key list) which would return a list of matches. After all, we have functions which _delete_ all matches from an alist. Does such a function already exist, perhaps in cl-*.el? Thanks! -- Alan Mackenzie (Nuremberg, Germany).
