I cannot see anyway to use direct execution of emacs lisp code in this (and nothing I have tried actually works). Any emacs-lisp code seems to get evaluated before running the block and *this* is not defined then.
As advertised, this works: #+name: wrap #+BEGIN_SRC emacs-lisp :var data="" (concat "====================\n" data "================\n")) #+END_SRC #+BEGIN_SRC python :post wrap(*this*) print 66 #+END_SRC #+RESULTS: : ==================== : 66 : ================ But I don't see a way in org-babel-ref-resolve to resolve emacs-lisp as a :post argument.
