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.

I think the capability folks would object to calling it a capability though. :-)

Two questions:

• Where to store the flag? It probably would cost 4 bytes per object.

• Which attributes are considered introspective?
