I've noticed that when using the `-` operator provided by the intarray extension, it appears to sort the results. Although I want the results sorted, I'd expect to have to additionally use the `sort` function it provides, as this behavior isn't documented. I don't want to rely on undocumented behavior, although it would simplify my queries to do so. Is the documentation lacking in this detail, or is it an unintended bug?
Thanks,
