Comment (by obenland):

 There is a way to retrieve a custom field value that is somewhat agnostic
 of current context: `post_custom()`
 ([https://core.trac.wordpress.org/browser/tags/3.9/src/wp-includes/post-
 template.php#L858 #]).

 I suppose we could introduce a function that is a bit more coherent with
 the naming conventions of template tags, and which optionally also accepts
 a post id:

 {{{
 #!php
 <?php
 /**
  * Retrieve the value for a post meta field.
  *
  * @since 4.0.0
  *
  * @param string $key Optional. The meta key to retrieve.
  * @param int $post_id Post ID. Optional.
  *
  * @return mixed The value of meta data field or an empty string.
  */
 function get_post_meta_value( $key, $post_id = 0 ) {
         return get_post_meta( get_post( $post_id )->ID, $key, true );
 }
 }}}

 But one could make the argument that it is not strictly necessary. If
 they're looking for a meta value of a specific post, they can use
 `get_post_meta()`. If they're looking for a meta value of the current
 post, they can use `post_custom()`.
