This class represents the result of resolution of a name.
It contains the object to which name was resolved, and the portion
of the name that has not been resolved.


A ResolveResult instance is not synchronized against concurrent
multithreaded access. Multiple threads trying to access and modify
a single ResolveResult instance should lock the object.
