E.g. I might have a service configuration registry object. The object behaves roughly like a dictionary. A certain user may be given read-only access to the registry.

Maybe every Python object should have a flag which can be set to prevent introspection -- like the current restricted execution mechanism, but on a per-object basis. Then any object could be used as a capability.
