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?
