Wow. That is pretty impressive. Although as far as the changes you needed to make are considered, my understanding from a brief skim of the page was that `__ass

  It depends on what you use from window. If no functions on `window` are called during initialization you could just use `__assumeDataProperty` on all the properties of `window` you access. If you call a function on `window` during initialization you would need to use `__residual` to emit the code into the residual program (assuming the call has no side effects on the heap that need to be seen by other initialization code). This is because otherwise Prepack cannot know how the abstract function would modify the heap (if it is an arbitrary function it could modify the global object for example), so it is not safe to execute.
