I expressed myself rather badly 

1.  First code

(defun test/set-property-at-heading ()
  "Function to be called at the beginning of an Org heading."
(interactive)
  (let ((el (org-element-at-point)))
    (org-set-property "foo" (org-element-property :title el))))
                                                         ^el is used
(org-map-entries #'test/set-property-at-heading)


2. Second code

(defun test/set-property-at-heading ()
  "Function to be called at the beginning of an Org heading."
  (interactive)
  (let ((el (org-element-at-point)))
        ^el is defined but not used.
    (org-set-property "New" "[ ]")))
(org-map-entries #'test/set-property-at-heading)

Is this a reference to the manual?
