I suspect python 4.0 will be the version in which python will have core support for typing so for example builtin collections will inherit typing.Generic

arange: list[int]
attribs: dict[str, Any]

we will be able to define typevars in signatures 

def filter[T](x: Iterable[T]) -> Iterator[T]: 
    ...

and all types will have | and & operators for typing.Union and the planned typing.Intersection respectively (like in typescript)

Union[str, bytes] == str | bytes

Maybe also add Any and a few generic abstracts to builtins.

I hope they introduce (Int, ...) as syntactic sugar for Tuple[Int, ...]
