The equivalent of your error suppressed example would be:
$var =3D $_GET['test'] ?? null;

I don't think it gains anyone much to have another form just to save four ch=
aracters (for the default `null`).

Someone mentioned an assignment version which isn't covered in niki's patch b=
ut would be a fairly trivial addition.

$var ??=3D expr;

Which essentially means:
if (!isset($var)) {
  $var =3D expr;
}

I'd kinda like that for completeness, but will vote for this with or without=
 the assignment version.
