• B f x can contain fields of type b f y as long as there exists a DistributiveT b instance. In particular, recursive usages of B f x are allowed.
• B f x can also contain usages of b f y under a Distributive h. For example, one could use a -> (B f x) as a field of B f x.

data family Y :: k

type TagSelf n b repbf = TagSelf' n b (Indexed b (n + 1)) repbf

We use the type-families to generically compute AllB c b. Intuitively, if b' f occurs inside b f, then we should just add AllB b' c to AllB b c. The problem is that if b is a recursive type, and b' is b, then ghc will choke and blow the stack (instead of computing a fixpoint).

So, we would like to behave differently when b = b' and add () instead of AllB b f to break the recursion. Our trick will be to use a type family to inspect RepN (b f) and distinguish recursive usages from non-recursive ones, tagging them with different types, so we can distinguish them in the instances.
