Re: Multiple Levels Of State
Whoever mentioned the MIT Lisp machine solution hit the nail on the head: if
(1) there is no notion of "nesting" of suspensions, but rather simply � pool of
tasks in various stages of completion which the user �an switch between at will,
and (2) every partially compl�ted task is represe�ted by a VISIBLE OBJECT on
the screen, then there is no issue about forgetting partially completed tasks,
being forced to complete them in the order they were started, etc., etc.  I believe
(at leas� I hope) the Star works this way, since all the experimental
multi-window systems at PARC do.
