| 2025-04-16 14:50:41 +0200 | <bwe> | So, I am starting now with: newtype State s a = State (s -> (a, s)) |

| 2025-04-16 14:49:13 +0200 | <[exa]> | which is annoying but that ensures that the typesystem can actually work with your stateful computation s->(s,a) specially, not just like some other function |
| 2025-04-16 14:48:50 +0200 | <[exa]> | yes you suddenly have to remove&add the "type tag" everywhere |
| 2025-04-16 14:46:24 +0200 | <bwe> | [exa]: that's interesting, shifting from type alias to newtype is bringing me headaches. The function body of the bind does not compile anymore, wherever I try to put State as data constructor. |

| 2025-04-16 14:27:56 +0200 | <[exa]> | bwe: as the next task try to think how to implement "set state" function and "get state" function |

| 2025-04-16 14:25:26 +0200 | <[exa]> | in particular the last line is basically what you just throw to the monad instance and it should work |
| 2025-04-16 14:24:32 +0200 | <[exa]> | anyway the rest of that seems ok |
| 2025-04-16 14:24:03 +0200 | <[exa]> | (doing instances on `type` aliases is .... well, complicated) |
| 2025-04-16 14:23:29 +0200 | <[exa]> | usually we do with `data` or `newtype`, in this case `newtype State ... = State (.. -> ..)` is probably the way |
| 2025-04-16 14:23:05 +0200 | <[exa]> | bwe: ok good, first you'll want to make instances on that so you need some kind of type tag for the "function" in your type there |
