Abstract:
We’re going to look at two somewhat more exotic type classes in the Haskell library ecosystem: Distributive and Representable. The former allows you to distribute one functor over another, the latter provides you with a notion of an index to access the elements. As an example, we’ll return once more to the grids used in Episodes 32 and 33 to describe the tic-tac-toe game, and we’ll see how some operations we used can be made more elegant in terms of these type classes. This episode is, however, self-contained; having seen the previous episodes is not required.
