**Distributive** is the dual of Traversable. **Links** - https://hackage.haskell.org/package/distributive-0.6.2.1/docs/Data-Distributive.html

We would need a symmetrical operation to `product` from Applicative but for Monad (or Bind) backed by a `let-operator`: `val (and*) : 'a t -> 'b t -> ('a *...

good first issue

Laws are missing. (But it should, maybe, await for the Test reorganisation)

test

See https://github.com/snowleopard/selective/pull/42/files It is possible to define `select` from `Traversable` and `Applicative`.

enhancement

Since we have `Free(r) Monad`, `Free Applicative` and `Free(r) Selective` we should have **Free Alternative**. **Links** - https://hackage.haskell.org/package/free-5.1.7/docs/Control-Alternative-Free.html
