For the case of strictness, I believe it can also be done without reparsing or AST walking [1]. Interestingly, using this approach it turns out that having the directive as the first statement offers no advantage in parsing whatsoever - it might just as well be at the end! : ) [1]: https://gist.github.com/zenparsing/7753590
