Only good things!

Drupal already works just fine on PHP 5, I've been using it that way for
ages, as have many others.  We've been holding back from using PHP 5's
complete bag of tricks because some users might not have it yet.  Now we
can let loose with the XML-parsing goodness and other fun toys. :)
