Yes - big-bang keeps track of the current state. And the various handlers are called to compute the new state. I can recommend: "big-bang: the world, universe, and network in the programming language" by Matthias Felleisen https://www.youtube.com/watch?v=ayoofXuKqMY The big-bang explanation starts at 12.30. /Jens Axel -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
