That's a very good point. Ideally exceptions will help there as it will simplify things significantly. But even without them, it should be possible to bypass execution. Considering I'm not targetting 7 (I've updated the RFC to hint this), we can choose what to do later depending on the exceptions result (whether to bypass execution in strict mode only, or for all calls).
