I think it's worth simplifying the access levels by removing `fileprivate`. 
Changing `private` to cover the common file-level cases brings no disadvantages 
IMO, since there's always the option of moving a declaration to a separate 
file. (I seem to disagree with a lot of opinions on here, that seem to want 
more fine grained access level control. I just don't see much tangible 
benefits, as composing protocols with the current access control levels is 
enough.)



I wouldn't do the compatibility mode since source conversion seems to work well 
enough. But I guess source compatibility is a hard goal.

My main question with all of this: Why is `private` a "soft default"? What's the point of a 
"soft default"? I think it should be _the_ default. `private` as default would promote 
encapsulation. It also just seems to make more sense than defining `internal` as the default, which is the 
"middle one".

What goes into a review?

The goal of the review process is to improve the proposal under review through 
constructive criticism and, eventually, determine the direction of Swift. When 
writing your review, here are some questions you might want to answer in your 
review:

What is your evaluation of the proposal?
Is the problem being addressed significant enough to warrant a change to Swift?
Does this proposal fit well with the feel and direction of Swift?
If you have used other languages or libraries with a similar feature, how do 
you feel that this proposal compares to those?
How much effort did you put into your review? A glance, a quick reading, or an 
in-depth study?
