Re: Fwd: [PHP-DEV] RFC: Anonymous Class Lexical Scope

One important thing I'd like to have here is importing the "outer" $this. e.g.: public function bar(){ return new class use($this as $that){ public function test(){ return $this->that; } }; } And I dislike how this would look with NikiC's proposal: return new class{ private $that = $this; }; Especially because "constant expressions" could change in the future and allow operations with $this, eg: An option could be what Joe proposed new class use($this as $that) (which I would particularly like if it allowed any kind of expression `new class use($this->foo->baz() + 10 as $that){}`) Or introduce a scope resolution keyword that works similarly to parent::. E.g.: public function bar(){ $foo = $this->getFoo(); return new class{ private $that = outer::$this; private $foo = outer::$foo; private $fooCall = outer::$this->getFoo(); }; } Thoughts? 2016-05-01 16:30 GMT+02:00 Björn Larsson <bjorn.x.larsson@telia.com>: > Hi, > > Nice and clear-cut RFC!
