[swift-evolution] [swift-evolution-announce] [Review] SE-0069: Mutability and Foundation Value Types

Comments:

- The sentences "These new struct types will be implemented in the Swift overlay. Immutable/mutable pairs (e.g. Data and MutableData) will become one mutable struct type” are a duplicate and may be a copy/paste error.

- I am unsure when a new struct type contains a mutable or immutable boxed object. 

- Is there a goal to eventually replace/remove the NS* versions completely within corelibs-foundation?
