Symbols

MzScheme provides two ways of generating an uninterned symbol, i.e., a symbol that is not eq?, eqv?, or equal? to any other symbol:

Regular (interned) symbols are only weakly held by the internal symbol table. This weakness can never affect the result of a eq?, eqv?, or equal? test, but a symbol placed into a weak box (see section 12.1) or used as the key in a weak hash table (see section 4.12) may disappear.
