What would improve usability in this area would be the chapter on AOP  
in the docs which hasn't been written yet.  I spent about a day poring  
through the source and the tests to find some examples of how to make  
all this work.  It's definitely non-obvious at the moment.  Some of the  
class names are really quite hideous, also.  That all being said, it  
seemed to work as advertised once I understood what was going on.  :)
