don't actually need a real stack I mean essentially it's just a partition of a lookup table like before we have a general lookup table but now you just partitioning the lookup table um sure right I guess like maybe the point here is that yeah ENS is really these rules and you can implement them efficiently this was what judo found and and it seems to work in practice and it kind of helps this stack like behavior that's the best the point of this and it's also optimal okay so what so returning to more interesting models which are not just
