[Help-Smalltalk] RootClass instead of nil

Hi,

I've made a small experiment yesterday, instead of nil as a superclass of
Object. I've putted "RootClass" (I don't like the name) why I've made
this refactoring: I don't like the behavior of
UndefinedObject>>subclass:
UndefinedObject>>subclass:instanceVariableNames:classVariableNames:poolDictionaries:
UndefinedObject>>subclass:classInstanceVariableNames:instanceVariableNames:classVariableNames:poolDictionaries:
UndefinedObject>>variableLongSubclass:classInstanceVariableNames:instanceVariableNames:classVariableNames:poolDictionaries:
...

They have nothing to do in UndefinedObject. This is just an idea that
I want to share with you ;)
All the remarks are welcome

Gwen
