hmm, when i go to edit it, i only have "fundamentals, strings, regular expressions" in the tags section. not really sure where declarative and advanced language features are coming from.

fixed

I don't mind at all :)

sorry guy, this comment slipped past me! approved :)

the Test failure message puts a comma between expected and instead got, it's a little misleading that way. You might have some trailing whitespace if it's failing only on the random tests. Hope that helps

Thanks for pointing that out! I've updated the description to include that trailing whitespace should be removed.
