If you can stand using method chains, I believe that role would be filled by the `takeWhile(_:)` method that Kevin Ballard (IIRC) wants to add to Sequence. (Although `takeWhile(_:)` would be greedy by default.) But honestly, other than distaste, I don't see much of a practical issue with putting an `if` or `guard` on the first line with a `break` in it. That still clusters the iteration logic at the top of the loop, even if it's not quite in a single statement. -- Brent Royal-Gordon Architechies _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
