    // to acquire is also the current tracker. If this is
    // the case, we have to avoid looking through current
    // tracker's children, and instead return the current
    // tracker.
    // A case where this check is important is e.g.
    //     for (int i = 0; i < 5; ++i) {
    //         int n = GENERATE(1, 2);

    //
    // without it, the code above creates 5 nested generators.
