There's not really such a thing as a "1st-class" array. Every array type needs to define its own indexing methods… and there are a lot of them! It's very tough to cover them all. You've just run into a method that's missing. As Tim suggests, you could write this method and submit a PR. I'm hoping to fix this eventually.
