> 	• What is your evaluation of the proposal?

+1.  I have run into problems with the current behavior a few times.  This proposal brings the behavior in-line with what I believe is best.

> 	• 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?

Yes.  It continues the trend of refining the behavior of Objetive-C and Cocoa bridging.

> 	• If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?

I have not worked in a language with the kind of first-class bridging Swift has.

> 	• How much effort did you put into your review? A glance, a quick reading, or an in-depth study?

I was the author of SE-0080 and wanted to include similar provisions in that proposal early on so I think it’s fair to say an in-depth study.  I’m happy to see the Foundation side of this topic receiving attention.
