WWW::Mechanize::FormFiller::Value::Default - Fill a fixed value into an empty HTML form field
=head1 SYNOPSIS
=for example begin
use WWW::Mechanize::FormFiller;
use WWW::Mechanize::FormFiller::Value::Default;
my $f = WWW::Mechanize::FormFiller->new();
# Create a default value for the HTML field "login"
# This will put "Corion" into the login field unless
# there already is some other text.
my $login = WWW::Mechanize::FormFiller::Value::Default->new( login => "Corion" );
$f->add_value( login => $login );
# Alternatively take the following shorthand, which adds the
# field to the list as well :
# "If there is no password, put 'secret' there"
my $password = $f->add_filler( password => Default => "secret" );
