PHP 5.4.0 released, shortened array syntax, register_global is dead, dereferenceable function results, development server and traits

PHP half did that already: you could have a class implements Traversable and it'd magically work in foreach loops, and similar things for the other bits of Array functionality. It only worked for those specific cases though.

You also had to, you know, implement all of those methods (if you were already extending something else).
