Yeah,
(let ((alist '((:foo . bar) (:baz buz))))
(cdr (assoc :foo alist)) ; -> bar
(cadr (assoc :baz alist))) ; -> buz
There isn't a lot of cost (well, one cons to nil) of using cadr or second instead of cdr. And then you could store other stuff in later positions of the list as well. When I only knew the definitions of assoc and pairlis, I mostly used cdr, but then in lisp code I've read, like you said, the cadr one seems more common in lots of places.
