Twigbridge and PHP7

I was playing around with my new PHP7 server and it turns out that twigbridge doens't play nice (or doesn't play at all).

InvalidArgumentException in ServiceProvider.php line 236:
Cannot instantiate Twig extension 'TwigBridge\Extension\Laravel\String': Class TwigBridge\Extension\Laravel\String does not exist

I've tried this on multiple 5.x versions and it's fine but just not in 7. Is it really just not compatible or can this be remedied?
