That is why binding membership and polymorphism together is a 
historical wrong turn. CLOS had it right but the world followed 
the Simula/Smalltalk path because of a nice metaphor (objects 
sending messages to each other).

My openmethods library allows you to add methods "from outside" 
and also supports dynamic loading: you can add new methods to 
existing classes and new classes to hierarchies that have 
methods. See the blog post that just came up.
