[drupal-devel] Why the object notation?

Hi! Drupal code uses object notation very often and I fail to see why it's better than associative arrays. We get $_POST data in arrays so we need to convert back and forth. We never use the class construct. So why the -> ? It seems like the change can be done with at most two simple regexp replaces. Regards NK Ps. I think it's OK to initialize an array by $array['foo'] = 'bar'; this needs two steps with object notation. Only $array[] needs initialization.
