filed: http://dev.clojure.org/jira/browse/CLJS-1887

Would this be considered a bug?

(apply distinct? (seq #{"-" \-})) ;; => false

I got a question, what should I do when I want to compile ClojureScript to a new JavaScript environment, which is not browser or Node.js , but something people customized with V8 ?

@jiyinyiyong why do you need to do something different?
