If you're lucky enought o be running WordPress on PHP 5.5, you can use generators for your post loops like this

gistfile1.php

<?php

// with the above we can now do things like this:
foreach ( posts_loop() as $p ) {
	get_template_part( 'content', 'page' );
	comments_template( '', true );
}

// put this below in your functions.php:

// post_loop generator
function posts_loop() {
	global $post;
	while (  have_posts() ) {
		the_post();
		yield $post;
	}
}
