real structure anymore since step C. You need to provide the original
structure as a third argument so `org-list-write-struct' can modify
buffer by set difference.
(let* ((struct (org-list-struct))
(old (copy-tree struct)))
(org-list-set-checkbox (line-beginning-position) struct "[X]")
(org-list-write-struct struct (org-list-parents-alist struct) old))
