It's interesting that AGAIN uses selections as checkpoints of a sort. I think that was probably the wrong idea as selections need to be made and remade to get them right, and so they aren't clear checkpoints, but interesting nevertheless. Though ignoring selections that you didn't act on might be sufficient to filter out those mistakes. The selection/target distinction is also another interesting path not taken. I encountered it in Oberon as well. I remember it feeling quite powerful, and yet I also was easily confused, like it was just a little too much to keep track of.
