Great to see this. I ended up writing this way after watching Brian Will's Why Object Oriented Programming is Bad [0]. Near the end he states we should be writing "procedural code" but that we should favor "pure functions". What I took away from this was that at a high level I should be able to reason about a problem procedurally but the solution should be composed of mostly pure functions.
