     False has only one instance, false, representing logical falsehood.
 
     Some methods are implemented here and in True, instead of the common

     However, remember that some messages to booleans are inline coded in
     the compilers (both interpreted and machine code). Therefore redefinition
     of some methods here will not have any effect on compiled code.
