In this function, there is
;; DEPRECATED header arguments specified as separate property at
;; point of definition
(let (val sym)
(org-babel-parse-multiple-vars
(delq nil
(mapcar
(lambda (header-arg)
(and (setq val (org-entry-get (point) header-arg t))
(cons (intern (concat ":" header-arg))
(org-babel-read val))))
(mapcar
#'symbol-name
(mapcar
#'car
(org-babel-combine-header-arg-lists
org-babel-common-header-args-w-values
(progn
(setq sym (intern (concat "org-babel-header-args:" lang)))
(and (boundp sym) (eval sym))))))))))
While the 3 `mapcar' calls could be turned into a single one, I wonder
if this snippet could be removed altogether instead. It has been
deprecated for 2 years already.
WDYT?
