title: Multiple toString methods?
body: <p>I had a problem in generating a comma seperated string from a list of objects.
  The problem is explained in this link <a href="https://stackoverflow.com/q/18743016/2606666">Convert string in list objects to comma separated</a></p>
  
  <p>I had solved this by using toString method. Previously i was using the toString() method as string builder for debugging purpose. As i am using it for the generation of comma seperated value i could not debug it as before.</p>
  
  <p>Is there anyway to accomplish both?</p>
