Laravel5 - cant get Sessions working

Im trying Laravel 5 and cant get Session working. Im inside a Controller and this is what ive done on an fresh setup and fresh controller:

\Request::session()->put('test', 'x');
var_dump(\Request::session()->get('test'));

This works as long as session is being written, and once you comment the first line there session value is gone on the next request.

Similarly, ive tried this Session:: instead of Request::session() and still same result.
