@dnolen: Looking though the issues I realized I made a comment on [CLJS-868](http://dev.clojure.org/jira/browse/CLJS-868) a while ago

Basically recursive calls can't do arity checks until the parsing of that function is complete. The most obvious solution seems to activate the arity checks when doing the second pass of the parser

I am not sure if that is the desired solution though

@kamn make sense to me
