Comment (by TimothyBlynJacobs):

 > At a guess, prior to priming the user cache in WP_Query::the_post()
 there will need to be a check for WP_Post objects, similar to that used in
 WP_Query::setup_postdata().

 I think that action makes sense to me as well. We could probably run an
 `array_map( 'get_post', $posts )` since the post IDs will need to be
 transformed into full `WP_Post` objects anyways by `::setup_postdata`.

 I think we should consider firing a `_doing_it_wrong` when using a
 `WP_Query` with `fields` set to `ids` ''and'' using the loop methods since
 those require fetching a post which defeats any performance optimization
 of making an `ids` query.
