Please note that you're extrapolating from my post: this isn't what I said. We still need this pattern: there's no way you're going to implement "undo" using only first-class functions, and I'm well aware of that. In some specific situations, though, we don't need it anymore, like when connecting a GUI "save" button to a "document.save" function.
