…nd DDC-1424. Improved DQL Parser, SQL Walker and Hydrators in general. Performance is generally improved by a factor of 20%. There is still more to be done, like remove the isMixed in ResultSetMapping, mainly because this query - SELECT u AS user FROM User u -, it should return an array('user' => [User object]), while currently it doesn't due to this before mentioned 'bug' in RSM. Will open a separate ticket for this. Also, UnitOfWork and Hydrators share code that could be abstracted/improved.
