I started attempting a version of @badkins [post here](https://racket.discourse.group/t/racket-set-performance/479) using `math/array`, but I didn't find as convenient a way as I would have liked to e.g. shift ever position one column to the right, with wraparound. (Though I could have written one on top of `array-transform`.)
