I agree. This would be an extremely useful feature, not only for game development, but also for web development. We often use continuations as a way to add state to the web, but this fails for two reasons: whenever the server restarts, or when we scale to multiple machines.
Note that for web development, you could also store a log of client responses on the client side and replay that whenever a request is made to get some kind of persistent session. This is only suited for lightweight use cases, of course. I've implemented a small demonstration as part of the "operational" package, it's the WebSessionState.lhs on http://projects.haskell.org/operational/examples.html Regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
