title: How to implement "or" in a scala filter?
body: <p>I am trying to implement an "or" filtering a list in scala.</p>
  
  <pre><code>    list.filter(_ % 3 ==0 || _ % 5 ==0)
  </code></pre>
  
  <p>but I am getting this error:</p>
  
  <p>error: wrong number of parameters; expected = 1</p>
  
  <p>So how can this be grouped as one parameter.</p>
