Comment (by birgire):

 In [attachment:"33045.6.patch"] for the {{{has_post_parent()}}} docs,
 there's currently:

 {{{
 * @return int

 }}}

 but it should be:

 {{{
  * @return bool
 }}}

 Regarding the naming, I would assume beforehand that
 {{{get_post_parent()}}} would return the post parent object, just as
 {{{get_post()}}}.

 But beside from that, we already have this function in core:


 {{{
 /**
  * Returns the ID of the post's parent.
  *
  * @since 3.1.0
  *
  * @param int|WP_Post $post Post ID or post object. Defaults to global
 $post.
  * @return int|false Post parent ID (which can be 0 if there is no
 parent), or false if the post does not exist.
  */
 function wp_get_post_parent_id( $post ) {
         $post = get_post( $post );
         if ( ! $post || is_wp_error( $post ) ) {
                 return false;
         }
         return (int) $post->post_parent;
 }

 }}}
