Access to underlying PDO object?

[hultberg]

In some projects I have had to integrate other database libraries which requires a PDO object. DBAL library API does not provide any way for developers (without reflection "hacks") to get the underlying PDO object that the DatabaseConnection object is provided. The DatabaseConnectionInterface also does not contain any method to get the underlying database connection library. The intention of the interface is to have an abstraction so that consumers don't need to worry about the underlying implementation. A complication might be the LazyDatabaseConnection class which creates the PDO object on demand. Any thoughts here?
