On constructor like: ``` class C { #[LazyInitialization] public function __construct(private readonly string $foo) { // ... init executes after first use, but all promoted properties are already initialized } } ``` or on specialized initializer: ``` class C { public function __construct(private readonly string $foo) { // do something light } #[LazyInitialization] private function initi(): void { // do something heavy } } ``` I don't know if this is a good example of doing the same thing or if it doesn't limit functionality, but for me, it is way more clean and easier to understand.
