Yeah, I hear you. There's definitely room for improvement here. I'm not sure what you mean by not greppable - the file is listed, as is the name of the particular koan. If there's a way to get line numbers displayed here that would be great.

I agree it does make it easier to solve when you can see what you're trying to evaluate to. It was actually a conscious decision to make that not be the case, because it seemed too easy to just fill in the blanks without thinking about what should go there.
