  <p>Hi, </p>
  
  <p>I'm trying to learn Ruby for fun at my spare time with the free <em>Programming Ruby</em> book. It is mostly fairly straight forward but I kept seeing notations like this <em>KaraokeSong#to_s</em>, which is not really explained in the earlier chapters of the book.</p>
  
  <p>I know it meant <em>&lt;class&gt;#&lt;method&gt;</em>  but it is something you can use in the code? or just a notation ruby programmers use to specifiy a method like <em>&lt;class&gt;::&lt;method&gt;</em> notation used by C++ programmers?</p>
