I think is that the $this->anArray['bar'] = 4;

Generate the following bytcode:

0  FETCH_OBJ_W                                      $0      'anArray'
1  ZEND_ASSIGN_DIM                                          $0, 'bar'

Will the folloing :

echo $this->anArray;
$this->anArray['bar'];

0  FETCH_OBJ_R                                     $0      'anArray'
1  ECHO
...



IMHO I think that the complexity of the VM is way to hight.
That is something I am strongly agree with Gilad Bracha on adding new
feature into a language:

Look at the last paragraph:
