2025-03-21 16:21:17 +0100 | <absence> | Here's the constraint by the way: https://hackage.haskell.org/package/effectful-core-2.5.1.0/docs/src/Effectful.Internal.Effect.html… |

2025-03-21 16:20:50 +0100 | <tomsmeding> | I'm not 100% sure this is what you are running into, but it has a similar "vibe" :p |
2025-03-21 16:20:33 +0100 | <tomsmeding> | you have to modify the class |
2025-03-21 16:20:29 +0100 | <tomsmeding> | no |
2025-03-21 16:20:11 +0100 | <absence> | Can I do that if the constraint and the function that needs it are defined in a third-party library? |
2025-03-21 16:19:58 +0100 | <tomsmeding> | if you don't know what I'm talking about, or don't know how it applies to your case, you'll have to share the definition of that Subset thing |
2025-03-21 16:19:35 +0100 | <tomsmeding> | the latter is normally _not_ what GHC does |
2025-03-21 16:19:26 +0100 | <tomsmeding> | that allows ghc to, given an `instance C A => C T` not only infer `C T` from `C A`, but furthermore conclude from evidence of `C T` that `C A` must also hold |
2025-03-21 16:18:44 +0100 | <tomsmeding> | absence: I have a feeling that this is an X-Y problem, and that the answer is a common-ish trick that I don't know a name for: define an associated type family to your class where the right-hand sides are precisely the instance contexts, then add that type family as a _superclass_ constraint to the class |

2025-03-21 16:16:55 +0100 | <absence> | When using a constraint called Subset, which takes two type-level lists, I find myself having to use "Subset (x : list1) (x : list2) => ..." instead of just "Subset list1 list2". Is there a way to convince the type checker that the x is superfluous? |
