Wrong on arrays.

Objects in PHP4 yes but while we want Drupal working still on PHP4, it's not a preference or priority any more at least for me. So if there is a minuscule performance penalty 'cos ancient PHP versions copy around objects so be it. As said, if I find the need for more advanced array function, I will use them and reimplement them for PHP4.
