Yes, I'm a big fan of cooperative threading. I haven't worked in C#, but I'd guess that yield() does the same thing as what I call Pause() in my code.

IEnumerable<string> Test() {
   yield return "dog";
   yield return "cat";
   yield return "mouse";
}
...
foreach(var item in Test())
   Console.WriteLine(item);

when the dictionary is changed the enumerator won't throw like it's supposed to

var d = new Dictionary<int, int>
{
    [1] = 1,
    [42] = 24,
};

foreach (var pair in d)
{
    Console.WriteLine($"{pair.Key} = {pair.Value}");
    d[42] *= 2;
}

1 = 1
