title: How to split a sentence into words by detecting space in clojure
body: <p>I want to split a sentence into words by detecting space. For instance,</p>
  
  <pre><code>user=&gt;(split "I like reading books")
  ["I" "like" "reading" "books"]
  </code></pre>
  
  <p>My code is </p>
  
  <pre><code>(use '[clojure.string :only(split triml)])
  </code></pre>
  
  <p>but when I compile it, I got "nil"</p>
  
  <pre><code>(load-file "file")
  nil  
  user=&gt;(split "I like reading books")
  ["I" "like" "reading" "books"]
  </code></pre>
  
  <p>How can I do to get rid of "nil" or is there any other ways to divide the sentences into words without slide-effect. Thank you!</p>
