How to use module loaded by composer in Laravel5?

Question

Composer

Downloaded the module https://packagist.org/packages/shuber/curl using composer. I'm trying to use it. What I do:
$curl = new \Curl();
I get an error:

FatalErrorException in File.php line 14: Class 'Curl' not found

The same thing worked in Laravel 4.2, switched to Laravel 5 - I get an error.
How to fix?
