> No, because you would just pass that extra argument around and nothing else would have to change. > Semantically, passing std.Io to every function is no different from making every Node.js function async and returning a promise. Zig shifts function coloring from blocking/non-blocking choice to io/non-io. > Complains are about how inconvenient it is to work with [blocking and non-blocking function handling] differences "Extra argument" in this case is not much different from "extra async keyword", because you can only run I/O functions when having std.Io in scope.
