>       * 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.

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.

Not personally. Most of my experience informing this decision relates to 
Objective-C code, and using Objective-C Foundation in Swift.

A full read, and following the initial discussion of value types in Swift for 
the past several months.
