We have a lot of `f . unDown` getting passed to higher-order functions that can't inline. In situations where GHC doesn't know that `f` has arity at least 1, the RTS will allocate a closure through wh…

These are lens-like combinators that could be used for manipulating arrows in funflow and porcupine. They are based on the code in the [profunctor-optics](https://hackage.haskell.org/package/profuncto…

I propose adding two more types related to `Enumeraion` and `IEnumeraion`.
```haskell
-- Inverse of Enumeration

This implementation of `promap` does not appear to unify with the type signature for the [`prom…

This would allow people to define lens-style `Fold`s, `Prism`s and `Iso`s without depending on lens.

Would be nice to have some implicit decoders as well.
Something like
```
class DefaultValueDecoder a where

Rows, if they are to be added, are probably calling…
