> What is your evaluation of the proposal?

Plenty of excellent points are made in the threads, which clearly
shows that there are many users who want to use the file based private
feature only, and many users who want to keep everything _really_
private, unless they need to be exposed at a file scope.

For this reason alone, reverting to Swift 2 behaviour is unwise.
Keeping `fileprivate` as is is also a better choice because it very
unambiguously expresses its meaning - a great quality Swift strives

Other reasons that lead me to the decision are the benefits of
encapsulation, churn. Others have made very good arguments already.

No other language that I know of behaves this way with the private.
That said, Swift should change things where it makes sense. However I
don't think this proposal is an improvement over how other languages
implement it.
