- Boolean comment:
- 'I have two instances in the Smalltalk system: true and false. I provide
- methods that are conditional on boolean values, such as conditional
- execution and loops, and conditional testing, such as conditional and and
- conditional or. I should say that I appear to provide those operations;
- my subclasses True and False actually provide those operations.' !
