Support for closures

[Green-Cat]

Zephir implemented support for closures.
So now they can be used like in php instead of using separate pseudo-classes.

Waiting full support of keyword "use" to delete pseudo-classes zephir-lang/zephir#888

Is it possible to implement this without the functionality of the use keyword? Or is there any other way to use callbacks right now that don't require use?

@kristoftorfs : Instead of using anonym function, you can use classic class.

Would you be so kind to give me an example? I'm trying to port a PHP (Phalcon) app to a Zephir extension, and I am having trouble injecting my services.

Boot.php:

$di = new FactoryDefault();
$di->setShared('db', new DatabaseService());

DatabaseService.php

class DatabaseService implements ServiceClosure {
    public function __invoke() {
        return new Mysql([
            'host' => 'localhost',
            'username' => 'root',
            'password' => 'secret',
            'dbname' => 'testdb'
        ]);
    }
}

When I try to get the service in the controller $this->getDI()->get('db') I get an instance of DatabaseService instead of the actual connection.
