It does decide who has access: any class that declares it as "delegated". In exactly the same way, "protected" gives access to any class that declares it as a "parent", and namespace visibility would give access to any class that declares itself in the same namespace. None of those actually limit access to a named list of classes, but all of them document an intended use, and catch mistakes where that intent isn't followed. Regards, -- Rowan Tommins [IMSoP]
