title: AS3: Static class versus Singleton
body: <p>I know SO pals are not fans of "versus" questions but... even rephrasing the tittle a bit, the versus part is still there, so, why hide it.</p>
  
  <p>Basically, I'd like to know when and why should I use a singleton or a static class, what can offer a singleton that a static class cant, and vice versa.</p>
  
  <p>For a long time I used both, and I cant see a reason why I shouldn't use one over the other.</p>
  
  <p>Thanks.</p>
