 Okay, I made this real quick and tested it, and it causes a critical error
 before getting to the END if you run it. Just add to a functions.php file.

 {{{#!php
 <?php
 add_action('init', function() {
         $test_values = ['', ' test ', null, false, [] ];
         echo '<h2>START</h2>';
         foreach($test_values as $index => $test_value) {
                 $test_output = untrailingslashit( $test_value );
                 echo '<h2>'.$index.' = '.$test_output.'</h2>';
         }
         echo '<h2>END</h2>';
 });
 }}}
