Subject: * Some syntactic sugar for attribute sets: allow {x.y.z = ...;} as a 
  shorthand for {x = {y = {z = ...;};};}.  This is especially useful   for
 NixOS configuration files, e.g.

    {
      services = {
        sshd = {
          enable = true;
          port = 2022;
        };
      };
    }

  can now be written as

    {
      services.sshd.enable = true;
      services.sshd.port = 2022;
    }

  However, it is currently not permitted to write

    {
      services.sshd = {enable = true;};
      services.sshd.port = 2022;
    }

  as this is considered a duplicate definition of `services.sshd'.
