title: Syntactical meaning of putting strings in parentheses
body: <p>I like to confuse myself with syntactical things and not to concentrate on really doing stuff. :)</p>
  
  <p>I know what I can do with this thing but I still want to know what is really happening under the hood.</p>
  
  <p>So... I just wonder what are the reasons and situations where putting strings inside parentheses is meaningful. I saw a method that returned something like </p>
  
  <pre><code>return (string1 + " " + string2);
  </code></pre>
