Another advantage of arrays over objects, is that arrays work almost
exactly the same in PHP4 as they do in PHP5. By ditching objects, it
should make it much easier to keep Drupal compatible with both of
these PHP versions.
For example, I just discovered today that in PHP5, object variables
are always created as references to the underlying object. So when you
copy an object, you're just copying the reference (unless you clone
the object). And when you pass the object to a function/method, you're
passing the reference (whether or not the parameter is specified as
'by reference'). In PHP4, however, object variables are not
references, unless this is explicitly specified. If we don't use
objects anymore, we won't have to worry about differing behaviours
(across PHP versions) such as this one.
Objects are one of the most poorly designed constructs in PHP4,
whereas arrays are one of the best and most powerful constructs in all
of PHP. I'm all for using arrays across the board in Drupal.
