Which brings me to a question: I'm not entirely clear on the relationship between and capabilities of Sam and Acme. Is the ability of Vis to select all instances of a regex and edit them all at once afterwards interactively (see e.g. https://asciinema.org/a/41361 https://asciinema.org/a/41361) Vis's own idea, or was it part of Acme?
