More specifically, this works since PHP 8.1, as shown by this handy tool:
https://3v4l.org/UTcfO

I believe it came about as almost a side-effect of
https://wiki.php.net/rfc/new_in_initializers although it also fits well
with enums (which are special objects), since it allows you to do things
like this:

enum DayOfWeek
{
    case MONDAY;
    case TUESDAY;
    case WEDNESDAY;
    case THURSDAY;
    case FRIDAY;
    case SATURDAY;
    case SUNDAY;
}
define('SCHEDULED_DAY', DayOfWeek::TUESDAY);
