They are very useful. I've used 24 of them, 86 times :) It is not really CL. cl-lib.el is in Elisp. So the cl- prefix is nothing to be afraid of, on the contrary it's great stuff :) Some of the stuff I don't know why I used tho, cl-caddr for example. Because there is a caddr, in subr.el... cl-caddr cl-case cl-concatenate cl-defun cl-digit-char-p cl-dolist cl-find-if cl-first cl-gensym cl-incf cl-labels cl-lib cl-loop cl-map cl-mapcan cl-mapcar cl-position cl-pushnew cl-remove cl-remove-if-not cl-return cl-set-exclusive-or cl-sort cl-subseq -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
