Setter	The "setter" of procedure that can be used in the LHS of an assignment.
Setter0	A special case of Setter, retricted to no arguments, except the RHS.
Setter1	A special case of Setter, retricted to one argument (plus the RHS).
SharedLocation	A Location suitable when Environment or Location can be access by multiple threads.
SimpleEnvironment	Concrete implementation of Environment.
Symbol	A Symbol is a name, usually in a specific Namespace.
Table2D	Maps 2 objects to another.
