WP_Query for a list of specific pages

This will return a list of specific pages in the same manner as posts are usually returned.

<?php $args = array( 'post_type' => 'page', 'post__in' => array( pagdeid1,pageid2,pageid3), 'orderby' => 'title', 'order' => 'asc', 'posts_per_page' => -1 );
$loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?>
    <?php the_title(); ?>
    <?php the_excerpt();?>
