=head1 NAME

Getopt::Yath::Option::AutoMap - Options that accept multiple values, but also
provide a default if no values are provided.

=head1 DESCRIPTION

This is a combination of 'Auto' and 'Map' types. The no-arg form C<--opt> will
add the default key+value pairs to the hash. The C<--opt=KEY=VAL> form will add
additional values.

=head1 SYNOPSIS

    option env_var => (
        field          => 'env_vars',
        short          => 'E',
        type           => 'Map',
        long_examples  => [' VAR=VAL'],
        short_examples => ['VAR=VAL', ' VAR=VAL'],
        description    => 'Set environment variables',
        autofill       => sub { +{ HOME => $ENV{HOME}, USER => $ENV{USER} } },
    );
