Points brought up elsewhere: * A range does not have direction, it is is an area of variation between lower and upper limits. * A range does not go from a larger amount to a smaller amount because it is not a sequence * Much of this problem goes away with striding (as Dave pointed out several times, sorry Dave) After consideration, I have been persuaded to the opinion that > stride(from: 0, to: -10, by: -1) and > (-9...0).reverse() both represent the numbers -9, -8,...,0 better than any alternatives I have offered. I still prefer the stride version for intent and clarity. That said, I also prefer my revised SE-0051 semantics for better representing what strides will attempt to do. -- Erica p.s. Thanks all for the patient explanations
