I understand the logic that got you there, but I find it incredibly counter-intuitive that striding by 2s over a range with odd endpoints should produce even numbers... I can't imagine any way I'd be convinced that was a good idea. > (0..<198).striding(by: -2): 1..<198 == 0...197 Odd > (1..<198).striding(by: -2): 1..<198 == 1...197 Odd > > -- E > -- Dave _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
