These are nonsensical in a true object-oriented language; since you can send any message to any object at any time, there is and can be no enforcement of protection.

Not to start a war here...

But why would it not be proper in a "true" OO lang for a class to be able to declare whether it wants to accept a message or not?

As an object, I might want to allow messages from some objects and reject messages from other objects.
