| 2025-02-11 08:10:41 +0100 | <haskellbridge> | <Bowuigi> Similar syntax can be achieved for the rest of the hierarchy using constraints, like how lens does it but with much less type aliases |

| 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 08:06:30 +0100 | <haskellbridge> | <thirdofmay18081814goya> what did you use it for? |
| 2025-02-11 08:06:26 +0100 | <haskellbridge> | <thirdofmay18081814goya> huh I haven't encountered a case where "f" is not the identity functor yet |

| 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 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 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 07:52:26 +0100 | <haskellbridge> | <thirdofmay18081814goya> hm I see |
| 2025-02-11 07:51:53 +0100 | <haskellbridge> | <Bowuigi> Like, to get effectful lenses over Kleisli or something like that |
| 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 07:49:21 +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 07:47:57 +0100 | <haskellbridge> | <thirdofmay18081814goya> it's not a rigorous question tbh, I'm just looking for personal opinions of instructive usages of the profunctor encoding |

| 2025-02-11 07:46:29 +0100 | <haskellbridge> | <Bowuigi> thirdofmay18081814goya cleanly wrt VL lenses or in general? |
| 2025-02-11 07:46:14 +0100 | <haskellbridge> | <thirdofmay18081814goya> we'd expect composition to be easier when using a higher abstraction no? |
| 2025-02-11 07:45:25 +0100 | <dminuoso> | Profunctors are an implementation detail here. |
| 2025-02-11 07:45:17 +0100 | <dminuoso> | They dont differ from van laarhoven or the mixed (van laarhoven + profunctor-style) in that sense. |
