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 =3D $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 =3D $this->getFoo();
     return new class{
          private $that =3D outer::$this;
          private $foo =3D outer::$foo;
          private $fooCall =3D outer::$this->getFoo();
     };
}

Thoughts?
