First of all, thanks for the great talk at HaskellX 18', I was wondering could you please prov…

The current implementations of the `coerce{S,T,A,B}` functions in `Optics.Coerce` sometimes require traversing data structures and hence are not guaranteed to be zero-cost, unlike `coerce`. For exampl…

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…

Hi there. Would you please consider renaming the `promap` method to `lens` (or something like this)?
This implementation of `promap` does not appear to unify with the type signature for the [`prom…

We currently mark everything as INLINE. Some of these are needed for rewrite rules or optimizing away profunctor typeclasses, but excessive use of them is known to slow down compilation and unnecessar…

I've been procrastinating on writing this issue for a while because every time I start writing it up it turns into a huge essay. So here is a short version that is missing many details, with the idea …

Let me write some thought on the design of optics, and especially
traversals, so that I don't forget again. All this should make its way
into a document
### Profunctor optics
When designing t…
