Hi, this looks like quite a serious bug to me (at least it messed up my project):
First taking the code taken from grimoire: clojurechess.position> (defn range "Returns a lazy seq of nums from start (inclusive) to end (exclusive), by step, where start defaults to 0, step to 1, and end to infinity. When step is equal to 0, returns an infinite sequence of start. When start is equal to end, returns empty list." {:added "1.0" :static true} ([] (range 0 Double/POSITIVE_INFINITY 1)) ([end] (range 0 end 1)) ([start end] (range start end 1)) ([start end step] (lazy-seq (let [b (chunk-buffer 32) comp (cond (or (zero? step) (= start end)) not= (pos? step) < (neg? step) >)] (loop [i start] (if (and (< (count b) 32) (comp i end)) (do (chunk-append b i) (recur (+ i step))) (chunk-cons (chunk b) (when (comp i end) (range i end step))))))))) WARNING: range already refers to: #'clojure.core/range in namespace: clojurechess.position, being replaced by: #'clojurechess.position/range #'clojurechess.position/range clojurechess.position> (range 0 11 2) (0 2 4 6 8 10) which is what I'd expect and relied on. Now, looking at the new code: clojurechess.position> (clojure.repl/source clojure.core/range) (defn range "Returns a lazy seq of nums from start (inclusive) to end (exclusive), by step, where start defaults to 0, step to 1, and end to infinity. When step is equal to 0, returns an infinite sequence of start. When start is equal to end, returns empty list." {:added "1.0" :static true} ([] (iterate inc' 0)) ([end] (if (instance? Long end) (clojure.lang.LongRange/create end) (clojure.lang.Range/create end))) ([start end] (if (and (instance? Long start) (instance? Long end)) (clojure.lang.LongRange/create start end) (clojure.lang.Range/create start end))) ([start end step] (if (and (instance? Long start) (instance? Long end) (instance? Long step)) (clojure.lang.LongRange/create start end step) (clojure.lang.Range/create start end step)))) nil clojurechess.position> (clojure.lang.Range/create 0 11 2) (0 2 4 6 8 10) clojurechess.position> (clojure.lang.LongRange/create 0 11 2) (0 2 4 6 8) clojurechess.position> (clojure.core/range 0 11 2) (0 2 4 6 8) So the culprit is clojure.lang.LongRange/create. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
