Is `range' a clojure function? If so, that's expected:
(info "(org) var") says:
,----
| The values passed to arguments can either be literal values,
| references, or Emacs Lisp code (see *note Emacs Lisp evaluation of
| variables: var.).
`----
[The syntax is wrong too: it should read
#+begin_src clojure :var c=(range 10)
(count c)
#+end_src
but it's not going to work unless you define an emacs-lisp function called range
and teach it to emacs.]
The following works (I don't have clojure installed here, so I replaced it with
scheme):
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(defun range (N)
(if (<= N 1)
(list N)
(nconc (range (- N 1)) (list N))))
#+END_SRC
#+begin_src scheme :var c=(range 10)
(define (count l)
(if (null? l)
0
(1+ (count (cdr l)))))
(count c)
#+end_src
#+RESULTS:
: 10
--8<---------------cut here---------------end--------------->8---
