Fix#1453, which went stale in 2000, which I unstaled in 2024, and which I finally got to. The code, and several unit tests, was substantially generated by AI, my first foray into that frontier.
Trait `ArrayEnabled` is not able to handle this function because it has too many array parameters. I would have liked to update it to handle this, but that seemed too difficult. I have let the code do its own array handling; it looks a little kludgey but seems to do the job. I may return to this at some point.
