Hello Orgers, please consider: Emacs -Q and evaluate the following
#+BEGIN_SRC emacs-lisp (org-babel-do-load-languages 'org-babel-load-languages '((calc . t) (emacs-lisp . t) )) #+END_SRC #+RESULTS: | (calc . t) | (emacs-lisp . t) | The following works as expected #+BEGIN_SRC calc :var V=3 V + 4 #+END_SRC But now we are getting: byte-code: Symbol's function definition is void: v! #+BEGIN_SRC calc :var v=3 v + 4 #+END_SRC Calc thinks that the variable v contains a function even though nothing should be undefined for v and when trying debug-on-entry for calc-var-value the expression (boundp v) returns t!? I'm stuck at this point, could you please have a look, I've no idea how to debug this further.
