The advantage of a class instead of an interface is that extends is 
required.  Since Java doesn't support multiple inheritance, 
opportunities for abuse are reduced.  I also think there is a mental 
barrier to is-a abstract class versus just a marker interface.  The 
former has design implications that many would not wish to break just to 
get a little operator overloading.
