Object::Trampoline: Follow the bouncing object.
You can find more information on the speaker's site:
The ability to re-bless an object is a powerful feature in Perl. Object::Trampoline handles very late binding of data types: when their methods are actually called. This can be helpful for breaking cycles in configuration dependencies or delaying actual construction of expensive objects until they are actually needed (e.g., database handles) or avoiding their construction altogether. Imagine starting a heavily-forked web sever without bringing your database to its knees!
