> 	* What is your evaluation of the proposal?

+1. This makes total sense. But I would recommend naming it “Never” for the same arguments as in the proposal.

> 	* Is the problem being addressed significant enough to warrant a change to Swift?

Yes, it simplifies the language by replacing a rarely used attribute by an elegant solution from the type system. I also love how Never could be used with typed throws.

> 	* Does this proposal fit well with the feel and direction of Swift?

Yep: simplification and elegance.

> 	* 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?

A good read.
