Description

EDITED: 2nd attempt to describe this - first one was confusing.

I don't understand why the setFetchMode() method of Doctrine\DBAL\Driver\PDOStatement drops any arguments passed to it. It means that PDO::FETCH_CLASS cannot be used with calls to fetch() and no warning is given until the point when the underlying \PDOStatement complains that no class has been specified.

Description	The fetch() method of Doctrine\DBAL\Statement does not accept any arguments. So trying to use fetch(PDO::FETCH_CLASS, 'ClassName') fails. But it doesn't fail until the fetch() method is called on the actual PDOStatement object - at which point it complains that a class name has not been given. There's probably a good reason for this, but I can't find any documentation as to why. It seems like it's intentional based on Doctrine\DBAL\Driver\PDOStatement, as the setFetchMode() function here does not pass on the arguments it receives.
