What would really be handy in a case like this is the ability to
create your own null-like values, guaranteed to be distinct from all
other values:
type hidden extends \php\basetypes\terminal {}
type default extends \php\basetypes\terminal {}
$checklist = hidden;
gettype($checklist); // 'hidden'
$checklist == hidden; // true
$checklist == deafult; // false
isset($checklist); // true
I realised after I wrote it that this particular train of thought has
basically led me to enums.
