Re: nested blocks in org

[mahmood sheikh]

with the given minimal example:
```
#+begin_parent
#+begin_child
#+end_child
#+end_parent
```
the code
```lisp
(org-block-map (lambda () (message "elem: %s" (org-element-at-point))))
```
goes through only the parent element and doesnt run the lambda on the
child block
the docstring of org-block-map says it iterates through src blocks but
it also goes through special blocks, albeit not nested ones, i
might've confused it for org-element-map as im not sure about the
later functions behavior.
