Would it make sense to have the rule twice, once for the correct version and once for post-2.20.0? That would produce working code for 2.19.40, while also taking care of files that were diligently converted with convert-ly up to 2.20.0 (the invalid code in those files is not the user's error but convert-ly's). Of course provided that the applying the rule twice doesn't ruin the code. Davide
