Bug report

Correct ones: https://github.com/python/typeshed/blob/8885cc870cc1089cba30a6ac6d4ea1e32c83cedb/stdlib/asyncio/staggered.pyi

There are several major problems:

1. loop: events.AbstractEventLoop = None, relies on very old mypy behaviour
2. coro_fns: typing.Iterable[typing.Callable[[], typing.Awaitable]] does not have type var for Awaitable, which is very hard to read: reader has to infer this type variable themself

This is a problem if people are using runtime type-checkers that will use __annotations__ from this function and not typeshed definitions.

Basically, we don't use annotations in the stdlib, but when we do: it should be correct.

I propose fixing it and even upgrading some other stuff:

1. It is a simple quality of life improvement
2. It only uses simple types
3. All python versions for backports are supported
4. It should not be edited again in the recent future
