This may be a language issue, but saying "I hope this causes a compilation failure" implies that you don't know if it does - this is probably why you got down voted, since the article very explicitly says that this doesn't cause compilation failure. You may have meant that you hoped it wouldn't do this - in that case you should have used a construction like "I'd hoped this would have caused a compilation failure".

Thank you so much for your reply! Your advice has been really helpful. I was confused about this.
