Wrong comments in DQL examples

[shesek]

In http://www.doctrine-project.org/docs/orm/2.0/en/reference/dql-doctrine-query-language.html, under "With COUNT DISTINCT:" and "With Arithmetic Expression in WHERE clause:", the comment after $query->getResult() says "array of ForumUser objects", which is probably wrong. It seems like it was copied from the previous examples and wasn't changed.
