> 	* What is your evaluation of the proposal?

No mistake: this is a pretty ugly solution to the problem. However, it *is* a problem that badly needs solving, and all the other solutions (like "always use the float logic and let the optimizer fix it up into integer logic") are far worse. So I believe this proposal should be accepted.

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

Yes. Striding simply doesn't work properly on floating-point types right now. That needs to be fixed.

> 	* 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?

Most languages I've used just let you write shitty floating-point code. It's nice to see Swift helping you write good floating-point code.

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

Quick reading and some private experiments.
