A 1-character infix operator is much cleaner to read than a 3-character name of a 2-parameter function.
But admittedly when you use 1-indexed arrays, any kind of modulo operator becomes pretty inconvenient a lot of the time (lots of futzing to avoid off-by-1 or boundary errors). So maybe it doesn’t matter in the Julia context.
That's precisely what it does!
