Every has a very ambiguous meaning in English. It could be understood as "every 3 values" as in 0, 3, 6, 9, etc... >> Am 10.04.2017 um 04:32 schrieb Ben Cohen via swift-evolution >> <swift-evolution@swift.org>: >> >> >>>> On Apr 8, 2017, at 5:41 PM, Brent Royal-Gordon <br...@architechies.com> >>>> wrote: >>>> >>>> On Apr 8, 2017, at 12:44 PM, Xiaodi Wu via swift-evolution >>>> <swift-evolution@swift.org> wrote: >>>> >>>> +1.
