TWIG: the new Drupal 8 template engine?
There is lot of activity around building a better theming experience for Drupal 8 at the moment. In fact, there will be a sprint on this topic tomorrow (friday) at Frontendunited in Amsterdam together with people in the United States. One option would be to provide a better, modern template engine. Something like TWIG perhaps. There is an issue on d.o for evaluating Twig using a module. Another reason why Twig might be a good choice: Fabien Potencier is behind it (lead Symfony developer).
