| 2025-01-16 06:05:58 +0100 | <jackdk> | Is it fair to characterise the problem as "I want to provide a set of keys, whether or not the keys are optional, and the types of their expected value, and get a JSON deserialiser for an object with those keys"? |

| 2025-01-16 06:04:28 +0100 | <jackdk> | I'm sorry, I still don't really understand what I'm looking at. Is `Wrap a` meant to be a sum type? Is the universe of keys meant to be finite? |

| 2025-01-16 05:14:23 +0100 | <Square> | I guess the parser would use a "Output Box" where box would be the sumtype housing the listing of type I mentioned in the paste. That "Box" would need existential quantifican (+ Typeable) as the enums would be arbitrary. |

| 2025-01-16 05:12:12 +0100 | <Square> | So I redifined my idea a bit, so ignore types mentioned in posts before the paste. |

| 2025-01-16 04:57:28 +0100 | <Square> | i will! Realized I needed to think a bit to write something comprehensive. |

| 2025-01-16 04:48:27 +0100 | <jackdk> | Thanks. Please mention me when it's ready so I get a beep |
| 2025-01-16 04:48:06 +0100 | <Square> | ok, ill do that |
| 2025-01-16 04:47:57 +0100 | <Square> | Say i want to deserialize a 'Map SomeKey Box'. 'data Box = forall a. Box a'. |
| 2025-01-16 04:47:40 +0100 | <jackdk> | If this is going to be a long explanation, you might want to use a pastebin |
| 2025-01-16 04:47:12 +0100 | <Square> | ops |
| 2025-01-16 04:47:11 +0100 | <Square> | Say i want to deserialize a Map SomeKey |
| 2025-01-16 04:46:39 +0100 | <Square> | ok |
| 2025-01-16 04:46:15 +0100 | <jackdk> | Can we jump to the concrete? What type are you trying to deserialise into and is the context defined anywhere (even perhaps outside of Haskell, like an API doc?) |
| 2025-01-16 04:46:08 +0100 | <Square> | quantified* |
| 2025-01-16 04:46:01 +0100 | <Square> | existentially qualified wrapper type* |
| 2025-01-16 04:45:33 +0100 | <Square> | jackdk, Hmm possibly. But I forgot to say that above mentioned types will be shuved into a existential type |

| 2025-01-16 04:42:36 +0100 | <jackdk> | Is the universe of possible contexts small enough to be represented by a family of newtypes? |
| 2025-01-16 04:41:23 +0100 | <Square> | jackdk, info about how fields should be deserialized. Like the presence of '"value":12' could get all sorts of type wrappings. 'Int', 'Maybe Int', 'SomeType (Maybe Int)' |
| 2025-01-16 04:38:38 +0100 | <jackdk> | Square: what sort of data is carried by the context? |

| 2025-01-16 04:37:34 +0100 | <Square> | I will be neading to create a JSON (de)serializer for a type that will require a context during the deserialization step. Aiui aeson doesn't support this. Sure I could roll my own with with some parser combinators, but I wonder if anyone sees a simpler approach? |
