Also, if the interface were less well known that Runnable, it would be 
helpful for a maintainer to see which methods were overridden.

public class Fubar implements ArgleBargle {

   public void doThing() {}

   @Override
   public void otherThing() {}

}

This makes one suspect that "doThing"is not part of the ArgleBargle 
interface, but something new added in Fubar.
