Does CodeIgniter support named query binding?
===

I checked the manual of CI and found it supports this kind of query binding:

    $sql = "SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?";
    $this->db->query($sql, array(3, 'live', 'Rick')); 

However I prefer the PDO style:

    $sql = "SELECT * FROM some_table WHERE id = :id AND status = :status  AND author = :author";

In this way the binding could be more flexible and sequence would not matter.

Does CI support that kind of binding?
