        Whether to enable/disable the experimental lua loader:

        If `true`: Enables the experimental Lua module loader:
          - overrides loadfile
          - adds the lua loader using the byte-compilation cache
          - adds the libs loader
          - removes the default Neovim loade

        If `false`: Disables the experimental Lua module loader:
          - removes the loaders
          - adds the default Neovim loader
      '';
    };
  };
