Hi, As a userland point of view on this: will this have a shorthand? i.e. what will happen if i leave out the second part? ie. $var = $_GET['test'] ?? ; would that be the same as $var = @$_GET['test']; The RFC isnt clear in this regard (or that the righthand side of the operator _is_ required... maybe it's me ?
