How to export generator function in TypeScript?

I have this example in JS:

export function* mySaga () {
    yield takeEvery('USER_FETCH_REQUESTED', fetchUser);
}

Can I rewrite it as an arrow function in TypeScript, something like this below?

export const mySaga* = () {
    yield takeEvery('USER_FETCH_REQUESTED', fetchUser);
}

Remember that TypeScript tries, mostly, to be JavaScript-plus-types (but early-adopting newer features). There is no arrow form of a generator function. However, Brendan Eich and Domenic Denicola are supposed to be working on one.

(The TypeScript specificaton just has a placeholder for its Generator Functions section [that link will rot as it's to a section number], and neither the issue related to implementing generators in TypeScript nor a related pull request mentions an arrow form.)
