Modular Extensions - HMVC version 5.4

Hi guys...

I'm a PHP noob and this questions might be trivial...

1, When I do var_dump($this) in two installation of CI, one is vanilla CI, the other is CI+HMVC, I get different result.
a. Can someone explain if this is on purpose or it's just inevitable...
b. Does this effect in any way the way someone code on CI.
c. Is it something that can be rectified by some code clean up? If yes, I'd like to try when I have the time.

2. In Base.php, the last line says

Code:

new CI

. A new object is instatiated without assigning it to a variable. How is it different from the common way ie.

Code:

$CI = new CI;

as I said, I'm a very novice programmer.
