> Throw in unknown, and you've got a hat trick, a holy trinity of nothingness!

`unknown` is a top type, since we're on the topic of nothingness it'd be remiss to not mention its dual, `never`.

The pair is also called `Any` and `Nothing` in some other languages.



INever implements IEnumerable, so ILove how you can iterate until the 12th of Never, and that's a long long time.
