I’ve done it before, but it doesn’t feel as explicit. It’s kind of magic for magic’s sake. Thinking back to when I first started using Elixir, I would have been very confused by this because they appear as two separate “declarations”. So I would be looking for what State was and ask, “why is it just referring back to the module?” not realizing that the module itself is the struct. On the contrary, defining it as a nested module gives the beginner a clear understanding of where %State{} actually came from.
