[swift-evolution] [SHORT Review] SE-0133: Rename `flatten()` to `joined()`

[David Hart]

> 	* What is your evaluation of the proposal?

+1 This makes total sense. I was going to voice my disagreement until I saw that I did not understand what the APIs did because of their names :D The renaming makes things much clearer.

> 	* 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?

Yes.

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

Even if some languages have flatten, it does seem like a special case of joined.

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

Quick read.
