I think they imagine a solution like this:

    // Spawn workers
    for _ := range 10 {
        go func() {
            for path := range workQueue {
                fp, err := os.Open(path)
                if err != nil { ... }
                defer fp.Close()
                // do work
            }
        }()
    }

    // Iterate files and give work to workers
    for _, path := range paths {
        workQueue <- path
    }

Maybe, but why would one introduce coupling between the worker queue and the work being done? That is a poor design.

Now we know why it was painful. What is interesting here is that the pain wasn't noticed as a signal that the design was off. I wonder why?

We should dive into that topic. I suspect at the heart of it lies why there is so much general dislike for Go as a language, with it being far less forgiving to poor choices than a lot of other popular languages.
