No. For me, classes not implementing __toArray() should keep current
behavior. That was what I had in mind when I wrote that __toArray() should
have a default standard implementation.
Same restrictions could be applied to this magic method:
http://us3.php.net/manual/en/language.oop5.magic.php#language.oop5.magic.tostring
By this, I mean, no exceptions should be thrown in this method and return
value MUST be an array.
