I missed you last comment, it's exactly what I mean. ------------------------------------------------------------------------ [2020-07-16 21:00:27] slavcopost at gmail dot com Alright, but w/o constructor promotion, when I define property it's auth initilized. I.e. ``` class A { public $a; } ``` does not require an additional initialization. ------------------------------------------------------------------------ [2020-07-16 20:57:33] nikic@php.net I can see the argument for giving $a a null default value though, because that's what normally happens with untyped properties. Right now constructor promotion gives you a property declaration that (for untyped properties) you cannot achieve in any other way, which is certainly odd, and not really intentional. ------------------------------------------------------------------------ [2020-07-16 20:53:04] nikic@php.net > That has never been mandatory, has it? No, and it's still not mandatory -- for example, you could also do a manual $this->a = 42 assignment if you like. The state of the parent class just needs to be initialized *somehow* and parent::__construct() is the most typical and most robust way to do so. ------------------------------------------------------------------------ [2020-07-16 20:41:17] slavcopost at gmail dot com > You are missing a parent::__construct() call.
