 There's an easy way to return boolean, integer (0), and an empty array.
 But what about an empty string?
 root\wp-includes\functions.php
 {{{
 /**
  * Returns an empty string.
  *
  * Useful for returning an empty string to filters easily.
  *
  * @since 3.0.0
  * @see __return_empty_string()
  * @return string Empty string
  */
 function __return_empty_string() {
         return '';
 }
 }}}
