I have tried the above by using M-e evaluation after M-x eev-beginner RET
I am fan of `while`:
;; this one
(let ((i '(2 3 5 8))
(no-go t))
(while no-go
(let ((item (pop i)))
(cond ((= item 5) (setq no-go nil))
(t (insert (format "\n%S" item)))))))

;; Or this one:
(let ((i '(2 3 5 8)))
(while (and i (not (= (car i) 5)))
(insert (format "\n%S" (car i)))
(setq i (cdr i))))
