Subject: = in ClojureScript differs from Clojure API for arities other than 2
Using ClojureScript f4c0de502c92ce710da923888d672f22213b902c (checked out on Thu Jan 19 2012) => (= 1) false ;; incorrect => (= 1 1) true => (= 1 1 2) true ;; incorrect => (= 1 1 1) true ;; correct, but by accident In Clojure and according to Clojure's API = is defined for all arities [1,2] => (= 1) true => (= 1 1) true => (= 1 1 2) false The source of this bug is that = is only implemented in ClojureScript for the 2 arity [3]. Combined with the javascript behaviour for superfluous arguments this leads to these unfortunate results. Implementing = for multi arities in ClojureScript by following the Clojure implementation should fix this. See for example the < predicate in ClojureScript [4]. My apologies for not using the bug tracker and not supplying a patch. I am not yet familiar with those systems. -Gijs [1] = API - http://clojure.github.com/clojure/clojure.core-api.html#clojure.core/= [2] = in clj - https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#L719 [3] = in cljs - https://github.com/clojure/clojurescript/blob/master/src/cljs/cljs/core.cljs#L180 [4] < in cljs as an example of a multi-arity predicate - https://github.com/clojure/clojurescript/blob/master/src/cljs/cljs/core.cljs#L801 -- You received this message because you are subscribed to the Google Groups "Clojure" group.
