| 2025-02-11 07:49:21 +0100 | <haskellbridge> | <Bowuigi> Ah, the nice part of the profunctor encoding is that you have access to the profunctor API. But since arrows are profunctors it doesn't make much of a difference wrt VL lenses |

| 2025-02-11 07:51:06 +0100 | <haskellbridge> | <Bowuigi> But switching the underlying profunctor that you use in a combined VL/profunctor optic could help yeah |
| 2025-02-11 07:51:53 +0100 | <haskellbridge> | <Bowuigi> Like, to get effectful lenses over Kleisli or something like that |
| 2025-02-11 07:52:26 +0100 | <haskellbridge> | <thirdofmay18081814goya> hm I see |
| 2025-02-11 07:59:09 +0100 | <haskellbridge> | <Bowuigi> I had a "type Optic p f s t a b = p a (f b) -> p s (f t)" sitting around my projects |
| 2025-02-11 07:59:56 +0100 | <haskellbridge> | <Bowuigi> Oddly enough the definition on profunctor-optics is "type Optic p s t a b = p a b -> p s t", which is equivalent |
| 2025-02-11 08:04:10 +0100 | <haskellbridge> | <Bowuigi> Namely, "Optic1 p f s t a b = Optic2 (\x y -> p x (f y)) s t a b" and "Optic2 p s t a b = Optic1 p Identity s t a b" |

| 2025-02-11 08:09:19 +0100 | <haskellbridge> | <Bowuigi> It's a bit nicer to write VL lenses with it. For example, the usual Lens (not generalizing over the profunctor) is just "forall f. Functor f => Optic (->) f s t a b" |

| 2025-02-11 08:22:26 +0100 | <dminuoso> | One should say, that VL lenses themselves are an ancient construct that is not used by `lens` either. |

| 2025-02-11 09:08:47 +0100 | <haskellbridge> | <thirdofmay18081814goya> I meant a particular action on it |
| 2025-02-11 09:10:05 +0100 | <ski> | (that `(a -> f b) -> f (a -> b)' would be kinda opposite of `(??) :: f (a -> b) -> a -> f b'. would only work for quite special `f's) |
