Compiler error when overriding functions from clojure.core

[pkozikow]

The following code:

(defn rand-int
  ([] (.nextInt rnd))
  ([mx] (.nextInt rnd mx)))

causes an exception at compile time (below). The code compiles and works fine when built with maven outside of intellij. Renaming the function to rand-integer makes the problem go away.

Interesting - if you :refer-clojure :exclude [rand-int] does that fix it?

[pkozikow]

Yes, that fixes it. Still, it's inconsistent with the maven behavior.

[cursive-ghost]

Yes, definitely, I was just curious - thanks.
