> 	https://github.com/apple/swift-evolution/blob/master/proposals/0095-any-as-existential.md
> 	* What is your evaluation of the proposal?

I think I like it and it seems straight-forward enough.

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

I cannot say if it is significant “enough” but I think it results in cleaner looking code that doesn’t end up reading as if generics are being used when they are not.

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

I believe so.

> 	* 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?

Minimal attention-paying during the discussions, 2 readings of the current proposal.
