Does this mean that roles are the recommended way to create immutable classes? Given that roles and classes now seem to differ only in their mutability, I can't see a reason why I would use class as my default object definer. I would prefer to use roles as they're closed by default, leaving "class" to be my powertool, if I need the power. Rob
