This is from the “unshadowable names” auditors plan. The idea was that  
a certain set of nouns (all those in the safeScope) *always* have the  
values they do, so auditors can rely on their behavior.

This system has been superseded by the “guard-based auditing” plan,  
which allows auditors to instead get a certain amount of information  
about what nouns *are* bound to, but E-on-Java has not been updated to  
acknowledge this.
