Yes, and it works quite well. I think it works well because zigs async requires you to think what is actually going on with the data structures at the low level (you have to understand what a frame is, that's a "new" low level construct on the level of "pointer" or "function"), once you get that and understand the control flow it is quite easy to see what's happening.
