I know you don't like to write in English, but could you please try to explain why the assignment makes a difference? The line scopeme doesn't work as expected, but each of a = scopeme puts scopeme scopeme.id has the desired effect. Why is it necessary to do something with the finalizer proc at the top level, even just sending it a message? Doing the same things inside the method "scopeme" doesn't work. I read about the definition of a conservative GC, but couldn't find a relation to this behavior. I could somehow understand if the difference is whether the finalizer proc itself is reachable from the root objects or not. This would explain why an assignment works at the top level, but not inside the method. What I don't understand though is why sending a message like "id" to the finalizer proc is making a difference. And even more puzzling to me is that this works only when doing it at the top level, but not inside the method. Regards, Pit
