Hi

I need feedback on the changes of daniel on tooDangerousClasses in  
ClassBuilder.
To test simply
What I did was to add an instance variable to Behavior at the end of  
the instance variable list and it did not crash
just recompiled the complete image.

Behavior actually can be redefined, as long as one doesn't move some  
of its first instance variables. ProtoObject, OTOH, probably can't be.


tooDangerousClasses
     "Return a list of class names which will not be modified in the  
public interface"
     ^#(
         "Object will break immediately"
         ProtoObject Object        "was Object"
         "Contexts and their superclasses"
         InstructionStream ContextPart BlockContext MethodContext
         "Superclasses of basic collections"
         Collection SequenceableCollection ArrayedCollection
         "Collections known to the VM"
         Array Bitmap String Symbol ByteArray CompiledMethod  
TranslatedMethod
         "Basic Numbers"
         Magnitude Number SmallInteger Float
         "Misc other"
         LookupKey Association Link Point Rectangle  
PositionableStream UndefinedObject
         "was LookupKey Association Link Point Rectangle Behavior  
PositionableStream UndefinedObject"
     )

I imagine that this is needed for trait refactoring.
