The foreach part has been working for hours.
But the Linq stuff? Nope, can't even get it to compile

class Foo // No interface here...
{
    public FooEnumerator GetEnumerator() => new();
}

class FooEnumerator // Nor here...
{
    private bool _done;
    public int Current => 42;
    public bool MoveNext()
    {
        if (_done) return false;
        _done = true;
        return true;
    }
}

Foo x = new();
foreach (int y in x)
{
    Console.WriteLine(y);
}

// Output: 42
