(cl-loop for i below 3 collect
  (let ((map (list (cons 0 3)
                   (cons 1 4)
                   (cons 2 5))))
    (map-delete map i)
    (null (map-elt map i))))
=> (nil t t) ; The first pair, i.e. '(0 . 3) is not permanently deleted.

I've used the word 'permantly' because it seems it is temporary
deleted:

(cl-loop for i below 3 collect
  (let ((map (list (cons 0 3)
                   (cons 1 4)
                   (cons 2 5))))
    (null (map-elt
           (map-delete map i)
           i))))
=> (t t t)

*) It happens just for alist, other maps are fine.
*) The test suite doesn't detect this issue because `test-map-delete'
   happen to delete just the 2rd element of the maps.
