> 	* What is your evaluation of the proposal?

+1.  It sets the stage for some very desirable type system features in the future.  There has already been extensive discussion on the topic and I don’t have anything new to add.

> 	* 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?


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

No, but I have seen examples from languages that allow this and found them very elegant.

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

Participated very heavily in the earlier threads on the topic and read the latest proposal.
