Unable to read remaining values after channel is closed

[codeReaper2001]

int main() {
    Chan<int> intChan;
    thread t1 = thread([&]() {
        for (int i = 0; i < 10; ++i) {
            intChan << i;
        }
        Close(intChan);
    });

    thread t2 = thread([&]() {
        for(int &x : intChan) {
            cout << x << endl;
        }
    });
    t1.join();
    t2.join();
}

the output is： Is this a bug or is my usage incorrect？
