I'm a bit concerned about what this does to introspection. With a dynamic language like Python, adding runtime methods does not interfere with your ability to enumerate all the methods supported by an object. With this opDispatch it's no longer possible for the compiler to know what list of methods a class responds to. So unless we add some way for a class to enumerate such things, opDispatch effectively kills any introspecting that requires knowing everything in a class. So that would make things like automatic wrapper generation difficult. And automatic mock classes. Anything else that requires enumerating methods? Also how does this interact with property syntax? --bb
