It's not an AST though. It's simply nested lists. Like JSON or XML but better. And the idea is to both have it automatic and manual. For example, `org-set-property' would work exactly as it does right now - interactively. But on the programming level it would use `read', `delete-sexp', `plist-put' and `prin1'. Isn't it much better to defer all the heavy lifting to the Elisp reader? Additionally, LISP readers are readily available outside of Emacs. It would ease other projects' Org-mode integration. Like mobile apps, taskwarrior, github, whatever - the people would be able to parse and modify Org with simply: import lisp_reader instead of grokking the full Org property syntax and all if its oddities and idiosyncrasies. Because the basic Org heading structure is genius simple. It's all the extra "stuff" than drags it down in terms of simplicity. > Parsing an Org document is a solved problem.

The motivation is to have Org look simpler by virtue of /being/ simpler. Compare (require 'org-element) and hours of grokking it and looking up docs to simply: (defun all-props () (save-excursion (goto-char (point-min)) (let (props) (while (re-search-forward "^(properties" nil t) (goto-char (match-beginning 0)) (push (read (current-buffer)) props)) (nreverse props)))) (mapcar (lambda (p) (assoc 'deadline (cdr p))) (all-props)) ;; => ;; ((deadline "<2016-02-26 Fri 17:00 +1w>") nil)
