length :: f a -> Int
We immediately know that values of the kind (* -> *) slot in to the value (f), with a kind checker to ensure we get it correct. Therefore, we can easily reason about the length of values of kind ((,) a)
I do find it hilarious that this discussion continued using the term "tuple" as if to make a reasonable point. KIND ERROR.
And it's doubly hilarious that that the above argument is put forward without any regard for picking an appropriate name for the concept, which most certainly is very different from "length" as used in everyday parlance, physics, mathematics, and any CS text-book on data-structures and algorithms I've ever seen.
