Hello, I've found a bug in org-babel. The simple code #+begin_src scheme (cons 1 2) #+end_src
Produces an error: #+begin_quote Debugger entered--Lisp error: (wrong-type-argument listp 2) org-babel-scheme--table-or-string("(1 . 2)") org-babel-execute:scheme("(cons 1 2)" ((:colname-names) (:rowname-names) (:result-params "replace") (:result-type . value) (:results .

If the results look like a list or tuple, then convert them into an Emacs-lisp table, otherwise return the results as a string." (let ((res (and results (org-babel-script-escape results)))) (cond ((proper-list-p res) (mapcar (lambda (el) (if (or (null el) (eq el 'null)) org-babel-scheme-null-to el)) res)) (t res)))) #+end_src should work on emacs older then Emacs 26 (proper-list-p not implemented here). -- With best regards, Igor Gajsin
