having fun with $this

Hi: It is still possible to re-asign $this in a number of ways examples <?php $this .= '123'; var_dump($this); //Notice: Undefined variable: this in this.php on line 3 //string(3) "123" <?php $this{1} = '123'; var_dump($this); /* array(1) { [1]=> string(3) "123" } */ or .. $this['foo'] = '123'; var_dump($this); In all those cases, I expect a fatal error : cannot re-asign $this. right ? or Im missing something ?
