Description
The type system needs to be extended to represent information about non-escaping
objects computed by escape analysis.

Comments
EVALUATION The type sytem will be changed to add a new class of types for "unique instances." These are objects which we have determined are unique and cannot alias any other objects, even objects of the same type.
