You can use the Common Lisp subset provided by cl.*\.el.
(push '(key . emacs) alist)
(setf (cdr (assoc 'key alist)) 'rms)
(setf alist (delete* 'key alist :test 'equal :key 'car))
Starting with GNU Emacs 24.2 you are allowed to use the cl functions in
end-user code. See <jwvehpvtdnb.fsf-monnier+emacs@gnu.org> for more
information.
