I find that I learn better and trust the resource more if earlier lessons have hooks for later topics. It helps my mind piece everything together. But to each their own.
In this case, it wasn't so much "deliberate hooks" as it is "I took a lot of care to not do this, but then when pull requests came in to add things that were left out, sometimes they introduced forward references that we didn't realize at the time."
Makes sense. I'll have to go through the rewritten parts again, as I'm having a heck of a time trying to pass the TcpStream object from Tokio into my actual service, as part of a personal learning exercise (https://github.com/mike-bourgeous/cliserver_rust/issues/6). I haven't broken down and asked online yet, partly out of sheer determination and partly because I'm in the middle of looking for a new place.
