- 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.
