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---

[O] Babel and clojure vars

[Lawrence Bottorff]

Once before I was wondering why :vars doesn't seem to work properly with
clojure. This works:

#+begin_src clojure :var a='(1 2 3 4 5)
(count a)
#+end_src

#+RESULTS:
: 5

as well as this

#+begin_src emacs-lisp :var a=(number-sequence 1 5)
a
#+end_src

#+RESULTS: num-seq-test1
| 1 | 2 | 3 | 4 | 5 |

but this is a no go. . . .

#+begin_src clojure c=(range 10)
(count c)
#+end_src

eval doesn't help, either.
