Error handling

doesNotUnderstand:, error:, primitiveFailed, halt, halt:, shouldNotImplement, subclassResponsibility

Porting tip:
These methods provide only the most basic error handling. Smalltalk/V uses implementedBySubclass n place of the Blue Book method subclassResponsibility, and does not support shouldNotImplement or halt:. All Smalltalk dialects provide additional error handling methods that are system- and operating system-specific.
