Maybe you could try either putting all of your functional definitions
into a single large code block, or you could write all of your functions
in their own named code blocks
#+source: foo1
#+begin_src emacs-lisp
(deufn foo1 () :foo1)
#+end_src
#+source: foo2
#+begin_src emacs-lisp
(deufn foo1 () :foo2)
#+end_src
and then use a single "functional-definitions" code block to collect all
of these functional definitions
#+source: functional-definitions
#+begin_src emacs-lisp
<<foo1>>
<<foo2>>
#+end_src
this single code block could then be easily included in other code
blocks.
#+begin_src emacs-lisp
<<functional-definitions>>
(def xyz (f1 (f2 foo))) ; produces bar
#+end_src
#+results:
: bar
I know this isn't exactly what you were after, but it does work under
the current system. I'd be interested to hear if other LP systems have
something analogous to a "concatenate" function...
