Possible usage of Linq queries in text format

[morgen2009]

Example 1.

/** @var IEnumerable $q */
$q = new Linq\Query(<<<LINQ
     from source in q
     where q => 2 and q < 8
LINQ);
$q->addTerm('source', [ 1, 2, 3, 4, 5, 6, 7, 8 ]);

Example 2. Partially executed as SQL command

/** @var IEnumerable $q */
$q = new Linq\Query(<<<LINQ
     from db.Product in p
     join db.Category in c on c.id = p.category_id
     where p.title like "%blue%" and myfunc(c.title)
LINQ);
$q->addTerm("db", $doctrine->getEntityManager());
$q->addTerm("myfunc", function($item) {
    return strpos("closed", $item) === false;
});
