In `MyClass.php`: ```php class MyClass { public static DateTimeImmutable $startup; public function horribleInitializationPractices() { self::$startup = new DateTimeImmutable(); } } MyClass::horribleInitializationPractices(); ``` That's really all there is to it. What you define as hacky is really normal/boring, and does not need special constructs. Also, it's generally not a good idea to sprinkle static mutable runtime-bound all over the place: it should be an exception, not a rule. >
