This is a neat idea. I suppose it is like saving your game in a video game. When you get killed, just start over at your last save.

- mahmud 17y agoI have read the paper when it came on LtU a while ago, and the analogy doesn't do the research justice. You could always persist side-effects until later use. That's what closures allow you to do. However, what the paper introduces is a new kind of "versioned memory"; Think of it as copy-on-write for the process' RAM, where certain procedures can make all the global side-effects they desire and keeping the changes only visible to themselves. Not only that, but it keeps a journal of state-change, so you can track how a particular variable changed over time. At least that's my understanding of it.
