I like fileprivate, if that’s the only change. On the other hand, if we want to 
consider a broader change, what about:

        private                 symbol visible within the current declaration 
(class, extension, etc).
        private(module) symbol visible within the current module.
        private(file)           symbol visible within the current file.
