Autoload twig extensions

[ornicar]

The twig doc says extensions should be autoloaded: http://www.twig-project.org/book/04-Extending-Twig

I can't achieve to autoload correctly the Debug extension using Symfony2 UniversalClassLoader. If I configure it this way:

$loader->registerPrefixes(array(
    'Twig_'  => __DIR__.'/vendor/twig-extensions',
));

Then Twig_Extension_Debug is autoloaded, but not Twig_Node_Debug, nor Twig_TokenParser_Debug. Because they live in an "Extension/" directory, and the class name doesn't contain "Extension".

How are we supposed to autoload these classes?
