Just to follow up, I'm now using the following to pretty up Clojure code in Emacs
#+begin_src emacs-lisp
;; symbols for some overlong function names
(eval-after-load 'clojure-mode
'(font-lock-add-keywords
'clojure-mode
(mapcar
(lambda (pair)
`(,(car pair)
(0 (progn (compose-region
(match-beginning 0) (match-end 0)
,(cadr pair))
nil))))
`(("\\<fn\\>" ,(make-char 'greek-iso8859-7 107))
("\\<comp\\>" ?∘)
("\\<partial\\>" ?þ)
("\\<complement\\>" ?¬)))))
#+end_src
I think the results look quite nice, a small example is attached
