New Comment:
There are several other ways to also re-assign $this, e.g.:
class Test {
public function __construct() {
var_dump($this);
/* Quirk comes in here by using the concation operator */
/* ${'this'} is not possible and results in an E_ERROR */
${'t' . 'his'} = 'Hello';
var_dump($this);
}
}
If any whether this should be fixed within the Engine, then Dmitry
would know so I'm re-assigning it to him for him to decide. As for a
documentation issue, I really don't belive we should document such
quirks in the official documentation else people will rely on such buggy
"features".
