Ciao Roberto, Whenever you remove a class that is still referenced in the system, an ObsoleteClass takes the place of the removed class. In the late-bound spirit of Smalltalk, the system allows removing the classes and dealing with the current references later.
If i may question the source of your problem: "a Dictionary (containing receivers of method calls, i.e., classes) that I need to serialize in a file (i.e., using Fuel)", are you sure you need to serialize the actual classes? or just the names? or even a description of the class within Ring? Think about what you are modeling with a Dictionary that holds <messages,set of receivers>, and maybe try to reify that concept.
