I was thinking about this, is there any reason why you can't replace a class's method with another method or install a method on an instance object that overrides the class's method, assuming that the method signature remains the same, the body has correct typing use of |this|, and the class is non-final? This seems to have the same integrity as method overriding in subclasses. Being able to do this (and possibly dynamically adding methods to classes) would bring the level of dynamicism that Mark had suggested with his ES4 sugar proposal (being able to create classes on the fly), but without destroying the fundamental ES4 typing/fixture system. This could be used to solve AOP as well, and bring a distinctly higher level of dynamicism which could be leveraged to progressively build, serialize (with proper introspection), and deserialize classes. Essentially, are there mutations to classes and object instances that do not effect integrity and do not violate explicit contracts against mutation (final annotation=no method mutations) that we could allow?
