This feature adds the `SessionValueResolver`. That means that you no longer have to rely on injecting a `SessionInterface` implementation via the constructor or getting this implementation from the `Request`. Regardless of method, it does not know about the `getFlashBag()`.
By adding the `Session` to the action arguments, you can now type-hint against the implementation rather than interface, which contains the `getFlashBag()`, making it accessible rather than using duck-typing.
_It should also feel less like injecting a service into the constructor which has a state or getting a service from the request._
**Old Situation**
```php
class Controller
{
public function __construct(SessionInterface $session) { /* ... */ }
public function fooAction(Request $request)
{
$this->get('session')->get(...);
$request->getSession()->get(...);
$this->session->get(...)
// duck-typing
$this->get('session')->getFlashBag();
$request->getSession()->getFlashBag();
$this->session->getFlashBag();
$this->addFlash(...);
}
}
```
**New Situation** _- The controller shortcut for flashbag could in theory be removed now_
```php
class Controller
{
public function fooAction(Session $session)
{
$session->get(...);
$session->getFlashBag();
}
}
```
