This tutorial us great I can't see why a language feature that counterintuitive us introduced. I played Dungeon games with more streightforward riddles. Perhaps this feature could be utilized for gaming quizzes.
I'm not sure what this comment is actually trying to say. the feature seems very intuitive and easy to understand.
It might seem intuitive to some people but my comment (which was the first after the post) said that its very prone to errors. Not saying much more than the other comments that were added in this discussion.
