I must note that this `where` does not belong to `case`.

for case x? where x < 10 in y { ... }
for x in y where x < 10 { ... }

First syntax is standard and won't go away. Second syntax is for-in 
specific, and is considered inconsistent.

* What is your evaluation of the proposal?

+1, because it removes piece of grammar that is unprecedented in other 
languages and that few people use.

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


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

Yes, especially with Swift 3!

* 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?

Followed the thread.
