Item 3 could not be enough, for instance:

<<<
class Example {
    public /* string */ $string;
    public function __construct() { static:: stringParameter
($this->string); }
    public static function stringParameter(string $string) {}
}

new Example;
>>>

It will fail because __construct() uses an uninitialized non-nullable
property.

Maybe it should throw a new Exception like UninitializedPropertyException
when you try to read a uninitialized property like this case.
