I am facing a problem when trying to GET a form with an option with an empty value. I.e. option1 has no value, option2 is 128 and option3 is 42. 
$url = "http://host/index.php?option1=&option2=128&option3=";
$option3 = 42;

$response = $useragent->get( $url . $option3 );

This works fine but is not very readable. So I tried the following: 
$url = "http://host/index.php";
$option3 = 42;

$response = $useragent->get(
                $url,
                  'option1' => '',
                  'option2' => 128,
                  'option3' => $option3,
);

This does not work. I tried '', undef and nothing as value of option1. None of this work. Can anyone tell me how to set an empty value for option1, please?
