Or cautiously build a NameSpace where every object you can refer to is safe to be refered.
But, what about #allInstances or ObjectMemory >> #nextObject ? (is #nextObject what I want? I want to walk the entire memory)
With this kind of messages I can escape the NameSpace and the jail of object references, get a big bunch of (inaccessible) objects and then #select: over it what I was looking for: FileDirectory, Smalltalk (and the world from there), etc.
Something else must be done with this messages... (are this problems solved with Squeak's NameSpaces?)
