     Myers indicated (* -- I can't remember whether it was in a paper or a
     private email) that a separate MVC system wasn't really needed in a
     constraint-based, prototype OO system like Garnet -- the constraint
     solver plays the role of the controller and the constraints defined
     the user's view of the underlying data or model.

     Amulet has special support for aggregation (the composition of
     individual objects into composites with a single interface -- lists of
     items and such) as well as the usual inheritance.  The prototype
     system can generate children from composite objects which inherit the
     behavior (but not the actual instances) of the aggregated components.

     This would directly support the copying of a section of text, a
     heading, etc. to another spot or document, and the subsequent
     alteration of that section without changing the original.
