Example of enhancing a popular CPAN module.
If a popular module doesn't do exactly what you want, it is often easy to add that functionality.
As an example, I created SQL::Abstract::More to add support of "ORDER BY" "GROUP BY", "LIMIT" and such.
Then I went on and created SQL::Abstract::Tree to support chainable queries ("how to join without using JOIN").
