> * What is your evaluation of the proposal?
+1 I concur with David Hart: Foundation becoming the base first-class cross platform library seemed concerning when Foundation was build from a paradigm of “Object Everything”. This fits far better with the Swift philosophy of value types where appropriate.
> * Is the problem being addressed significant enough to warrant a change to Swift?
Absolutely. As the basis for Swift Frameworks to come, I think it’s essential we do this right. This represents a clear streamlining of “legacy” Foundation with modern Swift.
> * Does this proposal fit well with the feel and direction of Swift?
Yes. This brings Foundation behaviour into line with Swift value-type behaviour.
> * If you have you used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?
Not personally. Most of my experience informing this decision relates to Objective-C code, and using Objective-C Foundation in Swift.
> * How much effort did you put into your review? A glance, a quick reading, or an in-depth study?
A full read, and following the initial discussion of value types in Swift for the past several months.
