Description
$parent = $query->from('Parent p')->leftJoin('p.Children')->execute()->first();
echo $parent['Children'][0]['Parent']['id'];
The second line will trigger doctrine to unnecessarily load a new instance of the parent from the database.
Also, when the query is run in HYDRATE_ARRAY mode, the child array contains no key for the parent, although I suppose this could be by design in order to avoid cyclic graphs.
Finally, a suggestion: it would be cool if doctrine could be configured to print a stacktrace whenever it lazily loads some data, to enable those of us developing for performance to more easily spot our mistakes.
