Please add your ideas to this list

remove instead of filter

     (filter (complement ?pred) ?coll) | 
     (filter #(not (?pred ?x)) ?coll)  | => (remove ?pred ?coll)

proxy when reify would suffice
unnecessary anonymous functions

  (fn [. ?arg] (?fun . ?arg))    |
  (fn* [. ?args] (?fun . ?args)) | => ?fun

as in (map #(inc %) coll) => (map inc coll)
