I don't understand, the error message you get is the error that occurred. the docstring from even? says it throws an exception if the argument is not and integer.
I would hope that anyone that has read the docstring for contains? would not use (contains? 'foo 'bar), because, uh, that just makes no sense. I mean that usage does not match what is indicated in the docstring 2009/11/9 Tiago Antão <tiagoan...@gmail.com>: > > Hi all, > > Just a question about the consistency of the API: > When one passes a "strange" (ie, wrong type) object to contains?, say > (contains?
