alt Hacker NewsOh, I see. The article is saying that async is required. I thought it was saying that parallelism is required. The way it's written makes it seem like there's a problem with the code sample, not that the code sample is correct.

The article later says (about the server/client example)

I gather that this is a quirk of the way async works in zig, because it would be correct in all the async runtimes I'm familiar with (e.g. python, js, golang).
My existing mental model is that "async" is just a syntactic tool to express concurrent programs. I think I'll have to learn more about how async works in zig.
