Slight tangent, but writing custom assembler code to make this go faster on the ARM chip makes me wonder how much optimization the Apple team has put into the Swift compiler for the A-series, work that has been going on for years for iOS. I suspect the answer is "a lot more than we realize" and it would be interesting to see this Golang comparison re-run on macOS/ARM (when available) and then compared to the same program written in Swift.
