How can you expose pkgs in the outputs?

I recently started to re-expose pkgs in the flakes output.
Mostly I just use x86_64-linux so I was just able to do inherit pkgs; how would I do this with flake-parts?

Try importing this module:

{ config, lib, withSystem, ... }: {
  _class = "flake"; # imports checking, optional
  flake.pkgsYolo = withSystem "x86_64-linux" ({ pkgs, ... }: pkgs );
  flake.pkgs = lib.mapAttrs 
    (system: config:
      # module arguments don't appear in config, so we use withSystem
      withSystem system ({ pkgs, ... }: pkgs)
    )
    config.allSystems;
}

nix-repl> pkgs.x86_64-linux.hello 
«derivation /nix/store/krmi4k907lh3wfrw3kr5w30ydwhnzrvw-hello-2.12.2.drv»

nix-repl> pkgsYolo.hello
«derivation /nix/store/krmi4k907lh3wfrw3kr5w30ydwhnzrvw-hello-2.12.2.drv»

or if you want to be fancy about it and distribute a module that does stuff like this, you could declare an option for flake.whatever, and don't hesitate to look at the sources for ideas.

I was finally able to test it and it works.
Thank you :)
