…face Context: Twig >= 1.38.0 or >= 2.7.0 Before: - Twig_Extension aliased to Twig\Extension\AbstractExtension After: - Twig\Extension\AbstractExtension aliased to Twig_Extension But we cannot just check for Twig\Extension\AbstractExtension instead of \Twig_Extension because users with old Twig version don't have this class. So, we check with the interface \Twig_ExtensionInterface because it exists since 1.0.0 and 2.0.0 and works with >= 1.38.0 and >= 2.7.0 because \Twig\Extension\ExtensionInterface is aliased to \Twig_ExtensionInterface
