[swift-evolution] [Review] SE-0055 Make unsafe pointer nullability explicit using Optional

[Matthew Johnson]

> 	* What is your evaluation of the proposal?

+1.  This is a very nice improvement for code that needs to work directly with pointers.

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

Yes.

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

Very much so.

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

It aligns well with languages that improve safety by explicitly modeling null. 

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

Followed the discussion and read the proposal.  I was very pleased to see Jordan propose this.
