On the aesthetic of a Java enum singleton

Surely java programmers these days use Bloch’s suggested form of singletons, e.g.

  1: 
  2: public enum Cupcake {
  3:     INSTANCE;
  4: 
  5:     private Foo someInternalStuff;
  6: 
  7:     private Cupcake() {
  8:         // get internal stuff ready
  9:     }
 10: 
 11:     public void doSomethingInteresting() {
 12:         // super exciting suff goes here
 13:     }
 14: 
 15: }

And then in our code we see Cupcake.INSTANCE strewn about.

Ok, that’s fine. But lately I found myself using “$” instead of that big fat “INSTANCE”. I just like how it looks. That “S” with a bar through it says “singleton” to me now.

  1: Cupcake.$.doAwesomeness(); // isn't that nice?

This is next to useless information about a personal preference and hardly worth a post. But there it is. :-)
