 * I see i can use “type”, but it’s not documented? I looked into the source code(
   wp-includes/comment.php:get_comments) but it seems “type” is not taken into account
   as a possibile argument.
 * Am I wrong?

 * Yes you’re incorrect, set the type to a valid comment type and it will work as
   expected..

 *     ```
       // Ignore this line - forum indent bug fix
       	elseif ( ! empty( $type ) )
       		$post_where .= $wpdb->prepare( 'comment_type = %s AND ', $type );
       ```
   
 * $type is extracted from the args array, arg keys become a variable with the same
   name, the value being that given arg’s value.
 * So feed the function a valid comment type and you’ll get what you’d expect to..

 * How is possibile that my get_comments function looks like this:
 *     ```
       /**
        * Retrieve a list of comments.
        *
        * The comment list can be for the blog as a whole or for an individual post.
        *
        * The list of comment arguments are 'status', 'orderby', 'comment_date_gmt',
        * 'order', 'number', 'offset', and 'post_id'.
        *
        * @since 2.7.0
        * @uses $wpdb
        *
        * @param mixed $args Optional. Array or string of options to override defaults.
        * @return array List of comments.

 * Not even similiar to the one you linked. I thought it was dued to the fact I’m
   referring to MU but on WP 2.9.2 also I have that. (wp-includes/comment.php) around
   line 185.

 * Apologies, appears there are changes in the newer version, and it’s missing from
   the 2.9 branch..
 * However, look at the following function..
    [http://core.trac.wordpress.org/browser/branches/2.9/wp-includes/comment.php#L575](http://core.trac.wordpress.org/browser/branches/2.9/wp-includes/comment.php#L575)
 *     ```
       seperate_comments()
       ```
   
 * Use `get_comments()` to grab the necessary comments, pass that into seperate 
   comments and it’ll split the array into comment types. Not a perfect solution,
   but the alternative would be write a custom query to pull what you want from 
   the DB..
 * eg.
 *     ```
       $comments_q = $wpdb->get_results( "SQL QUERY TO COMMENTS TABLE GOES HERE" );
       ```
   
 * [http://codex.wordpress.org/Function_Reference/wpdb_Class](http://codex.wordpress.org/Function_Reference/wpdb_Class)
 * This option would probably be better right now, because you could selectively
   grab just what you need, rather then grabbing all comments and filtering out 
   what you don’t want.

 * Thanks 🙂
 * By now I’ve modified the core file adding the “type” filter support, I hate doing
   that because with the next update I’d forget it for sure 🙁

 * The new code will be in the next version though… 😉 so it won’t matter.. i can’t
   see another minor release(ie. 2.9.x) happening before 3.0 now.
