> The one thing I dislike about Elixir is the confusion caused by how some libraries execute their functionality in-process and others spawn a supervision tree and message pass. It's my assumption that needless process-starting is from classic OO developers trying to get something closer to the objects they're used to. I'm not sure separating the client and API logic in tutorials would necessarily stop them from doing this. People who are hellbent on shoehorning familiar idioms into an unfamiliar language are going to do so regardless. But I see what you're saying. I think it's more important to drill home that modules and processes have nothing to do with each other. I still catch myself conflating them once in a while three years in and it's caused the most confusion while trying to teach friends (although I'm not a particularly good teacher).
