Unique/Isolated; A way to declare or require that an object (both 
struct and class) cannot have more than one reference.

For instance, it is perfectly fine to move an AA across thread 
boundaries if there is only one reference to it. But in the 
general you can't because you can't proof there is.

This touches on @live a bit, but @live is put on functions 
whereas I want it on objects (class+structs).
