 `wp_cache_get()` includes the forth parameter `$found`. It's a boolean
 passed by reference to allow developers to determine whether the returned
 value `false` indicates a populated cache with the value `false`.

 {{{#!php
 <?php
 wp_cache_set( 'ticket-57741', false );

 $found = false;
 $result = wp_cache_get( 'ticket-57741', '', false, $found );
 var_dump( $found, $result );
 // true, false

 $found = false;
 $result = wp_cache_get( 'invalid-key', '', false, $found );
 var_dump( $found, $result );
 // false, false
 }}}


 `wp_cache_get_multiple()` does not include a similar parameter and could
 benefit from one. Instead of been a boolean, it would be an array passed
 by reference.

 At the conclusion of the function running, the `$found` array would be of
 the form:

 {{{
 array(
   'set-key' => true,
   'unset-key' => false,
 )
 }}}
