title: Scheme How to Take the first item in the List?
body: <p>Say I want to take the first item of the lists <code>'(4 3 1) '(5 6 8)</code></p>
  
  <p>I want something like this</p>
  
  <pre><code>(first '(4 3 1) '(5 6 8))
  </code></pre>
  
  <p>should return me the first item</p>
  
  <pre><code>(4 3 1) 
  </code></pre>
  
  <p>as result. Is there something like this in scheme build-in function I can call ?</p>
  
  <p>car doesn't work, as it only returns me the first item inside 1 list</p>
  
  <p>list-ref doesn't work, same reason above, returns me 1 item inside the list</p>
  
  <p>How can I do that? if I need to write it myself this first function ?</p>
