inheritance semantics in Self 4.0
I've seen a number of references to various changes that have been
made to Self's inheritance semantics since Self 3.0. For example,
elimination of parent priorities, a new theory of slot privacy, new
idioms for sharing behavior.
I gather that the changes are slated to appear in Self 4.0. I've
tried to locate a written description of the new semantics, perhaps
including an outline of the latest lookup algorithm, but I haven't
found it. Am I missing something? If so, I'd appreciate a pointer.
Or perhaps someone in the know would be willing to post a summary.
