** => most recent top-level result
The ** Symbol is bound to the normal form of the expression most recently entered at the top level. When attempting to evaluate a term that does not have a normal form -- like
(cdr ())
-- the binding of ** remains unchanged.
*symbols* => symbol table
The *symbols* variable is bound to the symbol table of the interpreter. Its normal form is a list of all Symbols known to the interpreter.
