AFAICS, $this should not be altered(reasigned) in anyway.
this should "Fatal error : cannot reassign $this" I guess.

Description:
------------
Using $this as parameter is possible, but when using it (except from
printing it out) $this referes to itself
It is also possible to change $this via reference.
The object name seems to get changed - but when using it it works fine.
Reproduce code:
---------------
<?php
class foo {
function __construct($this) {
printf("ctor \$this parameter is: %s\n",
var_export($this, 1));
self::overwrite($this);
printf("Returning from self::overwrite \$this is: %s",
get_class($this));
$this->hello();
}
function overwrite(&$obj) {
$obj = new stdclass;
printf("self::overwrite \$this is: %s\n",
get_class($this));
}
function hello() {
printf(" ...lier! \$this is still %s\n",
get_class($this));
}
}
$obj = new foo("Hello world");
var_dump($obj);
Actual result:
--------------
ctor $this parameter is: 'Hello world'
self::overwrite $this is: foo
Returning from self::overwrite $this is: stdClass ...lier! $this is
still foo
object(foo)#1 (0) {
}
