Boolean messages

&, and:, eqv::, ifFalse:, ifFalse:ifTrue:, ifTrue:, ifTrue:ifFalse:, not, or:, xor:, |

Porting tip:All Smalltalk dialects implement the same set of Boolean messages. Users should be aware that in some cases the compiler can optimize by in-lining control operations rather than implementing them as message sends. This is usually transparent unless there is an attempt to subclass or modify one of the Boolean classes.
