----------------------------------------------------------------- Boolean is an abstract class defining the protocol for logic testing operations and conditional control structures for the logical values represented by its subclasses True and False. Boolean redefines #new so no instances of Boolean can be created. It also redefines several messages in the 'copying' protocol to ensure that only one instance of each of its subclasses True (the global true, logical assertion) and False (the global false, logical negation) exist in the system.
