What does "$" mean in Left $ A x. Why does not write it as "Left A x"?
Isn't "Either" the same thing as AorB in
data AorB = Aconstructor Int | Bconstructor IntI want two separate types A and B along with a third type which is their Union. Is that not possible?In my actual case, I have more than two types. So I would like a way to take the union of an arbitrarily number of types.data Union = A1 | A2 | ...where each of A1, A2, ... has its own data declaration.
