type family Any :: k where ...

The type constructor Any is type to which you can unsafely coerce any lifted type, and back. More concretely, for a lifted type t and value x :: t, -- unsafeCoerce (unsafeCoerce x :: Any) :: t is equivalent to x.

fromAny :: Any -> a

Coerce Any to a boxed value. This is generally unsafe and it is your responsibility to ensure that the type you're coercing into is the original type that the Any is coerced from.

toAny :: a -> Any

Coerce any boxed value into Any.
