class (Monoidal (<--) source (:*:) (:*:) t, Extendable source t) => Comonad t source

Let f :: (Extendable t, Extractable t) => t a -> b
Let g :: (Extendable t, Extractable t) => t a -> b

When providing a new instance, you should ensure it satisfies:
* Left identity: extend extract ≡ identity
* Right identity: extract . extend f ≡ f
* Associativity: extend f . extend g ≡ extend (f . extend g)
