My comment was worded a bit too harshly, sorry about that, I certainly wouldn't have worded that way in a personal message.
As I mentioned the hexadecimal printing coincidence is a neat fact, I was just excited when clicking the link to find a novel bitset idea. In my disappointment to find the standard bitset (albeit with 16-bit limbs) I reacted a bit too harshly. And as per https://xkcd.com/1053/, just because something isn't new to me doesn't mean it's not new to anyone.
