Extra parenthesis are not removed when used with lib.optionals

[SuperSandro2000]

The following snippet

  [ ]
  ++ (lib.optionals (cyrus_sasl != null) [ "--enable-cyrus-sasl=yes" ])
  ++ (lib.optionals (gnutls != null) ["--enable-gnutls=yes" "--enable-nss=no"])
  ++ (lib.optionals stdenv.isDarwin ["--disable-gtkspell" "--disable-vv"]);

should be converted to

  [ ]
  ++ lib.optionals (cyrus_sasl != null) [ "--enable-cyrus-sasl=yes" ]
  ++ lib.optionals (gnutls != null) ["--enable-gnutls=yes" "--enable-nss=no"]
  ++ lib.optionals stdenv.isDarwin ["--disable-gtkspell" "--disable-vv"];

Thanks for the report! Currently statix does not remove useless parentheses in binary expressions, like x ++ (y), I am waiting for some parsing changes around operator precedence to land before implementing this.
