submit_form_ok() and follow_link_ok() assign what are apparently error messages to a local variable $error but never use the variable for anything.
$ ack -Q '$error'
Mechanize.pm:309: my $error;
Mechanize.pm:311: $error = 'No matching form found';
Mechanize.pm:318: $error = $response->as_string;
Mechanize.pm:367: my $error;
Mechanize.pm:369: $error = 'No matching link found';
Mechanize.pm:376: $error = $response->as_string;
