That was the point of that section of the paper, that doing the straightforward thing leads to a muddle: "At this point, it becomes clear that our original strategy of updating the UI from the individual setter methods is probably not tenable in the long run." A little later: "As we have seen, even a conceptually very simple application such as a temperature converter quickly attracts significant complexity with non-obvious trade-offs once the requirements of an interactive version of that application are taken into account." The fact that you need to create these centralised updater methods is non-obvious, and leads to a bunch of related non-local changes. Also a muddle. "This complexity is not the result of a complicated domain model, but rather of the architectural embellishments required to move data from location to location in order to keep the different parts of the application (model, user interface, persistence) synchronized. In the next section, we will look at a mechanism for simplifying this kind of overhead." > ReactJS (uses HOM like Objective-Smalltalk) ReactJS uses Higher Order Messaging?
