newtype Bazaar p a b t Source #

This is used to characterize a `Traversal`.

a.k.a. indexed Cartesian store comonad, indexed Kleene store comonad, or an indexed `FunList`.

http://twanvl.nl/blog/haskell/non-regular1

A `Bazaar` is like a `Traversal` that has already been applied to some structure.

Where a ``Context` a b t` holds an `a` and a function from `b` to `t`, a ``Bazaar` a b t` holds `N` `a`s and a function from `N` `b`s to `t`, (where `N` might be infinite).

Mnemonically, a `Bazaar` holds many stores and you can easily add more.

This is a final encoding of `Bazaar`.

newtype BazaarT p (g :: * -> *) a b t Source #

`BazaarT` is like `Bazaar`, except that it provides a questionable `Contravariant` instance To protect this instance it relies on the soundness of another `Contravariant` type, and usage conventions.

For example. This lets us write a suitably polymorphic and lazy `taking`, but there must be a better way!
