 The parsing necessarily comes with a performance overhead, but only if you really use a list of parameters.
 There are two special binding types that describe a list of integers or strings:

--   ``\Doctrine\DBAL\Connection::PARAM_STR_ARRAY``
+-   ``\Doctrine\DBAL\ArrayParameterType::INTEGER``

 Using one of these constants as a type you can activate the SQLParser inside Doctrine that rewrites
