title: When to Use the Decorator Pattern?
body: <p>I am going over my design patterns, and one pattern I have yet to seriously use in my coding is the Decorator Pattern. </p>
  
  <p>I understand the pattern, but what I would love to know are some good concrete examples of times in the real world that the decorator pattern is the best/optimal/elegant solution.  Specific situations where the need for the decorator pattern is really handy.</p>
  
  <p>Thanks.</p>
