Currently when constructing an ArrayObject it isn't possible to specify whether 
or not you would like recursion to take place, thus traversing the array 
structure and creating ArrayObject instances in multi-dimensional arrays. 

Whilst I appreciate that this is standard behavior, being given the option when 
constructing would be very useful as you wouldn't then be required to extend the 
class for what is quite a common use-case. I appreciate it's easy to extend the 
class and code in the recursion, but I feel a param on construct would be 
equally as useful (perhaps even as part of the bitwise flags).

Failing this, the documentation should at the very least be updated to include 
an example of instantiating the class with a multi-dimensional array to show 
that any arrays within the one passed to the constructor will not be converted 
by ArrayObject. 

Test script:
---------------
$array = array('one' => 1, 'fruit' => array('lemon' => 'bitter', 'orange' => 'sweet'));

$obj = new ArrayObject($array);

$obj->fuit->orange; // null
$obj->fuit['orange'] // 'sweet'
