💻 Code

export function* asd() {
    yield 2;
    yield 3;
    return 1
}

🙁 Actual behavior

This is allowed, the following code is emitted even though it requires inference:

export declare function asd(): Generator<2 | 3, number, unknown>;

🙂 Expected behavior

This is disallowed (probably all generator functions)
