If you're lucky enough to be using any version of PHP 5 with WordPress ( 100% chance! ) You can do this:

gistfile1.php

<?php

$posts = new posts_loop();
foreach( $posts as $id => $post ) {
	the_title();
	// etc...
}


// put this below in your functions.php:
/**
 * WordPress Main Posts Loop Iterator
 */
class posts_loop implements Iterator {
	public function __construct() { }

	function rewind() {
		rewind_posts();
	}

	function current() {
		global $post;
		return $post;
	}

	function key() {
		global $post;
		return $post->ID;
	}

	function next() {
		the_post();
	}

	function valid() {
		return have_posts();
	}
}
