Forgive my terrible macroing but, if your really must, you can: (defmacro ord-compare [a ord b] `(if (or (= > ~ord) (= < ~ord)) (~ord ~a ~b) "Use > or < to compare.")) (ord-compare 3 > 2) Edit: there's also incanter.inflix, which will translate inflix notation into clojure like notation. https://github.com/liebke/incanter/blob/e1235cf9ffa2e528823eefa4187ed7210b156bd5/modules/incanter-core/src/incanter/infix.clj https://github.com/liebke/incanter/blob/e1235cf9ffa2e528823e... Check out the tests for how to use it: https://github.com/liebke/incanter/blob/aa71f1135c3beb7bf7a4dc060c479b8680dd6c95/modules/incanter-core/test/incanter/infix_tests.clj https://github.com/liebke/incanter/blob/aa71f1135c3beb7bf7a4... A good example: ; $= translates inflix to prefix notation. ($= 3 <= (5 * 2/7)) ;will give you false.
