Finally! Someone does a concise explanation of specialArgs and _module.args, which I have only see as mystery magic that I've needed to reverse engineer in fear.

Hey hello and thanks for this very detailed guide. As I'm re-reading it after about a year, I noticed that in first steps of setting up the flake.nix you use this line:

outputs = { self, nixpkgs, ... }@inputs: {

while later (on this page) you switch to this line:

outputs = inputs@{ self, nixpkgs, ... }: {

Is there any difference? Could you maybe add some explanation in the code?

These two syntax forms are semantically equivalent — it's a fundamental concept you'll encounter while learning the Nix language. I'd highly recommend checking out the official tutorial at https://nix.dev/tutorials/nix-language.
