title: Issue with Clojure 'contains'
body: <p>I am going through some Clojure tutorials using Closure Box, and entered the following code:</p>
  
  <pre><code>user&gt; (def stooges (vector "Moe" "Larry" "Curly"))
  #'user/stooges
  user&gt; (contains? stooges "Moe")
  false
  </code></pre>
  
  <p>Shouldn't this evaluate to TRUE ? Any help is appreciated.</p>
