Thank you for the suggestion, but it returns a symbol and not the
string. In the more complex setting I'm playing with I need a string

By the way, this is something that I really don't understand about sbe:
what is allowed as functions inside it? If I do the simple

--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp :var z="bar"
  (let ((y (org-sbe test1 (x z))))
--8<---------------cut here---------------end--------------->8---

then it fails, telling me 'z' does not exist. But for some reason,
adding "intern" lets 'z' get the "bar" value and be converted to the bar

Is there documentation about what is allowed in sbe? (I had another
similar problem recently, see
