[redux-saga] Correct typing for function yielding all effect

[AndrzejSala]

What is the current behavior?
I would like to add flow typing for the following function:

export default function* segmentUploadSagas() {
  yield all([watchRecreateSegment(), watchUploadSegment()]);
}

For function which yields effects normaly I use
: Saga<void>
, but it doesn't work

Also I tried this one, which is working fine for yield [...effects], but calling array of effects without all is causing warning:
: Generator<any, void, any>
