 The REST API controllers have a fair amount of procedural transformation
 code like this:

 {{{
 /**
  * Prepend internal property prefix to query parameters to match our
 response fields.
  *
  * @param  string $query_param
  * @return string $normalized
  */
 protected function normalize_query_param( $query_param ) {
         $prefix = 'comment_';

         switch ( $query_param ) {
                 case 'id':
                         $normalized = $prefix . 'ID';
                         break;
                 case 'post':
                         $normalized = $prefix . 'post_ID';
                         break;
                 case 'parent':
                         $normalized = $prefix . 'parent';
                         break;
                 default:
                         $normalized = $prefix . $query_param;
                         break;
         }

         return $normalized;
 }
 }}}

 What if I could just define some `transform_to` argument when registering
 my request arguments, and have the request data transformed before it gets
 to my callback?
