Possible Doctrine Param Converter

PostController1.php

<?php

class PostController
{
    /**
     * @Route("/posts/{slug}")
     * @DoctrineParam("post", expr="repository.findOneBySlug(slug)")
     */
    public function showAction(Post $post)
    {
    }
}

PostController2.php

<?php

/**
 * Maybe have a more global way of doing this to?
 * 
 * @DoctrineParamNamed("find_by_slug", expr="repository.findOneBySlug(slug)")
 */
class PostController
{
    /**
     * @Route("/posts/{slug}")
     * @DoctrineParam("post", convert_with="find_by_slug")
     */
    public function showAction(Post $post)
    {
    }
}

Looks good :)
