which works fine. Question: Where is the elisp code that does this writing of `org-element-parse-buffer` output to file? I'm stumped on how to do just simple file read-write in elisp. It seems to only want to work with live buffers. For example, how would I redirect `(org-element-parse-buffer)` into, say,  `(append-to-file 1 (buffer-size) "test-ast.txt")`
