I'm having a hard time understanding why I'm getting an Unexpected T_PAAMAYIM_NEKUDOTAYIM
error in the following code, which seems perfecly valid to me...

{
return self::$id;
}
}
function instance($xpto = null)
{

echo var_dump(instance('prod')->getMyID()) . "\n"; // prod
echo var_dump(instance()->getMyID()) . "\n"; // null
In prior versions however, I can't do $result::$id = strval($xpto);
