I for one agree with Mike Fleming that Obj-C like Categories would
be an excellent addition to the Java language. They are an
extremely useful tool; as much or more than Interfaces.
And Mike, I wouldn't give-in so easily to the security concern. I
have a feeling categories could be a security issue. However, since
this is a new language, I don't see why we couldn't allow class
designers to declare if a class "allows" categorization or not.
Or if a category-added method were restricted to the public interface.
Obviously, there would you be some things you couldn't do, but that is
the whole point of privacy, isn't it, to make some things impossible?
