I think it can be done but I dont think it should be part of Ruby itself. Why not implement it in a class that can be inherited by objects needing this. If this is too restrictive (inheritance cannot be used for your own purposes) aspect-oriented programming might be one natural way to add these capabilities to classes. If you take this path you might want to check out AspectR in RAA. Regards, Robert
