I honestly don’t believe that this a common style in the Cocoa community. I’m not a member of the “old guard” having only come into this world 10 years ago with the iPhone, but just take a look at this delegate method in Objective-C: - (void)locationManager:(CLLocationManager *)manager rangingBeaconsDidFailForRegion:(CLBeaconRegion *)region withError:(NSError *)error; 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. 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. > 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. Again, I dispute the idea (having no data but my own :P) that 80-col limits are common in this community. l8r Sean _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
