title: Difference between method and function in Scala
body: <p>I read <em><a href="http://www.naildrivin5.com/scalatour/wiki_pages/ScalaFunctions" rel="noreferrer">Scala Functions</a></em> (part of <em>Another tour of Scala</em>). In that post he stated:</p>
  
  <blockquote>
    <p>Methods and functions are not the same thing</p>
  </blockquote>
  
  <p>But he didn't explain anything about it. What was he trying to say?</p>
