 Hello.

 In some (edge?) cases we would need a unique identifier when we retrieve
 metas. For example, `get_post_custom_values( '_yolo', $post->ID )` will
 return:

 {{{
 Array
 (
     [0] => foo
     [1] => bar
 )
 }}}

 while the following, with the `meta_id` as array key, would be helpful
 imho:

 {{{
 Array
 (
     [1022] => foo
     [1029] => bar
 )
 }}}

 The modification is trivial in `update_meta_cache()`, and some other
 functions would only need something like `metas[0]` => `reset( metas )`.
