If I evaluate this:

#+name: = myfun1
#+begin_src clojure=C2=A0
(defn myfun1
=C2=A0 [ ]
=C2=A0 9)
#+end_src

#+RESULTS: myfun1
: #'clojure-noob.core/myfun1

then this

#+begin_src= clojure
(inc (myfun1))
#+end_src

<= div>#+RESULTS:
: 10

I've got t= he right answer, but I've totally bypassed the :var functionality. In m= y elisp example

#+begin_src emacs-lisp :var m= yx=3D(mylist1)
(mapcar '1+ myx)
#+end_src

#+RESULTS:
| 2 | 3 | 4 | 5 |

=
it seems to be as you say, i.e., the function needs to be evalua= ted, and, yes, the mylist1 function in parens does the trick. But this
<= /div>

#+begin_src clojure :var i=3D(myfun1)
(inc i)
#+end_src

produces this= in *Messages*:

eval: Symbol=E2=80=99s functi= on definition is void: myfun1

However, this
<= div>
#+name: myfun1-test2
#+begin_src clojure= =C2=A0
(myfun1)
#+end_src

#+RE= SULTS: myfun1-test2
: 9

does final= ly get seen and evaluated:

#+begin_src clojur= e :var i=3Dmyfun1-test2
(inc i)
#+end_src
#+RESULTS:
: 10

But th= is adds an extra step just to use :var. I'm guessing regular Lisp and m= aybe Scheme (geiser) know about=C2=A0var i=3D(myfun1), . Will test, but I&#= 39;ve got to swap out my .emacs.d first. As far as noweb is concerned, doin= g <<myfun1>> doesn't win me anything, does it? It's the= same as (myfun1) above.

Aloha Lawrence,

I don't know the Clojure dialect, but I think the problem is that the myfun1 source code block returns a function.=C2=A0 It doesn't evaluate<= br> the function and return a result, which is I think what you are
expecting.

You can use noweb expansion of myfun1 to define the function inside
another source code block, then use the function in the normal way in
the source code block (or in the session, if you have that set).

Or, you might change the myfun1 source code block to return a list,
rather than a function (if I'm reading Clojure correctly):

#+name: myfun1
#+begin_source clojure
[8 9]
#+end_source

hth,
Tom
