    // Given this

    interface One {
    kind: 'one';
    value: 1;
    }

    interface Two {
    kind: 'two';
    value: 2;
    }

    // ... and this alias
    type Number = One | Two;

    // ... can the `kind` values be expressed as a type without having to explicitly do this:
    type NumberKinds = 'one' | 'two';
