The module Data::Page lacks a simple property that is useful when you need to build SQL queries with a LIMIT clause under MySql: how many records should you skip to reach the first record of current page? The answer is $self->first - 1 records. This isn't obvious to remember and not so clear at first sight when you read in a query, so I added a property that implements this functionality. A little example:

...
$pager = Data::Page::Extended->new($total_records,
                                   $page_size,
                                   $current_page);
$sth = $dbh->prepare(q{select * from table
                        where rec_date <= ?
                        order by rec_date
                        limit ?,?});
$sth->execute($date, $pager->skipped_items, $page_size);
