Agreed.  Reading this thread, almost everyone’s presented actual use cases would be fixed if we could do something functionally equivalent to private(type) (even if that’s not the best syntax).  If we could have the ability to write extensions for a type throughout a module and access its private properties (and private subtypes, methods, etc.), then the ugliness introduced by fileprivate would be all but eliminated.  That’s an access level I would love.

I do want to mention, though, that while I would enjoy C++-style type-level private, I don’t want protected.  The rationale for avoiding that in Swift is fantastic.
