Mixins and java annotations...

I'm reading some stuff about java 1.5 annotations and I'm trying to come out
with a small but usefull example of how they relate to mixins.

Here are some links I'm currently reading:

• The New Holy Trinity
  
• Annotations and AOP
  
• AOP Mixin Implementation with AspectJ 5 and JSE 5.0
  
• Mixins and Introductions (JBoss)
  
• Annotations + Bytecode Generation == Mixins
