well to use setters it has to be "foo.something = else", because JS can't override plain old local bindings -- not since "with" was sent to the cornfield anyway. Once you do that, you can indeed have a framework that generates getters and setters, which is exactly what Vue 2 does. Switch to proxies instead of get/set and you have Vue 3 -- the signals API is pretty much identical to the Vue composition API.
