> Of course, to each their own style--I certainly wouldn't want Swift to force everyone to write lines of certain lengths. But 80-character lines is a common style, and I would say that a corollary of "to each their own" is that Swift's grammar should be usable and useful whether or not you adhere to such style choices.<br>

That’s well over 80 characters all by itself. This fits on my screen in a single line - and I work on a 15” MBP with room for my dock always visible on the side along with Xcode’s sidebar open! On a typical desktop-sized screen, 80-col lines must be comically short.<br>
<br>
I don’t know why it should be assumed that people are adhering to a so-called standard that dates back to terminal screens that didn’t have color.<br>

> If the chief advantage of `where` is that it (quoting someone above) allows one to "understand as much as possible about the control flow of the loop from a single line of code," then we ought perhaps to question its appropriateness when the majority of its benefits [by which I mean, based on your examples and Sean's, more than half of the instances in which it is used] cannot be realized in a very common coding style.<br>
<br>
</span>Again, I dispute the idea (having no data but my own :P) that 80-col limits are common in this community.<br>
