Nah, forget it, it does not work that way...

UndefinedObject class>>someSuperObsolete
     ^ObsoleteSubclasses

would not reach this class var definition though:

   (Behavior classVarNames includes: #ObsoleteSubclasses and: [
      UndefinedObject class allSuperclasses includes: Behavior].

Which is confirmed by:

   UndefinedObject class allClassVarNames includes: #ObsoleteSubclasses.

There is definitely some trick here...
