On that vein, I would often like to know whether the function I can is creating a task/thread/greenlet/whatever that will continue executing, concurrently, after it returns. Making that be part of the signature is approximately called “structured concurrency”, and Zig’s design seems to conflate that with taking an io parameter. This seems a bit disappointing to me.
