The runes are mostly "just because", but there is a reason.
Ideally, I would have written:
type Nil = unique symbol
Which would ensure the Nil type wouldn't match with anything but itself. Unfortunately, the compiler doesn't allow unique symbol other than on const variables initialised with Symbol(). So I needed some meaningless symbols.
I could also have done
type Nil = "nil"
But then it would have looked like the string meant something.
