Make if-not example clearer, fix the answer keys I felt the example wasn't very clear as the conditional returned the quoted form of `doom` when it evaluated to true or false. This way the user needs to find a value that satisfies the if-not conditional so it returns `doom` and not `more-doom`. 2013-11-22 19:52:20 +00:00			`(= 'doom (if-not (zero? __)`
