If you want an optional value, then do the same as all python code and do x: Optional[int] = None

I was investigating why
Optionaldefault was broken (ie.x: Optional[int] = 1would default toNone) and ended up refactoring a good bunch of the code, finding out that defaults seemed to be overall quite broken.
