- SystemDictionary comment:
- 'I am a special form of dictionary. Typically I only have one instance,
- called "Smalltalk", which is known to the Smalltalk interpreter. I define
- several methods that are "system" related, such as #quitPrimitive.
- My instance also helps keep track of dependencies between objects.' !
