Gordon - the application of such capability is arguable that is true... but the capability to pass references is absolute. One could for instance... create a custom event handler that passes a reference to the private/internal function to event subscribers. If this were truly and absolute - composition, introspection and reflection would be forfeit.
So - if I can add a quickie. If your class makes something private, it will only be accessible within your class unless you provide a reference passing mechanism (e.g. a setter/getter).
