Aloha Lawrence,
I don't know the Clojure dialect, but I think the problem is that the
myfun1 source code block returns a function. It doesn't evaluate
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
