2024-11-20 17:32:44 +0100 <bwe> `withDict :: Dict (IntoGeneral a) -> (IntoGeneral a => SiteVariant) -> SiteVariant`
2024-11-20 17:31:26 +0100 <bwe> I don't, because `withDict :: Dict c -> (c => r) -> r` is possible and `Dict (IntoGeneral a)` comes into play hereā€¦

2024-11-20 17:26:47 +0100 <bwe> dminuoso: Do I have to define HasDict instances now?
2024-11-20 17:25:52 +0100 <bwe> dminuoso: `Dict (IntoGeneral a)` in the function head of `fromDBEntry` remains, because that is the dict for `withDict dict`?

2024-11-20 17:20:37 +0100 <mari-estel> huh come on, functors are not that scary
2024-11-20 17:20:31 +0100 <Square2> Not sure I can, but yeah I see your point.
2024-11-20 17:20:23 +0100ubert(~Thunderbi@178.115.41.15.wireless.dyn.drei.com) (Remote host closed the connection)
2024-11-20 17:19:53 +0100 <dminuoso> Avoid the constructs entirely.
2024-11-20 17:19:46 +0100 <dminuoso> Square2: My best advice, avoid the words `functor` and `monad`.
2024-11-20 17:19:30 +0100 <Square2> dminuoso, Yes, I've been there. But, yeah. To begin with, they'll only need to grasp basic functor/monad constructs. I feel it should be doable for people who got MSc's in comp science.
2024-11-20 17:19:23 +0100 <dminuoso> bwe: So if you bring your HasGeneral typeclass back, make instances for `HasGeneral SiteA` and `HasGeneral SiteB`

2024-11-20 17:18:31 +0100 <bwe> Yeah, I had that gut feeling already.
2024-11-20 17:18:29 +0100 <dminuoso> Might as well go all-in!
2024-11-20 17:18:13 +0100 <dminuoso> Well, we're of course overcomplicating all of this. I did not know this was an XY problem yesterday. ;-)
2024-11-20 17:17:15 +0100 <bwe> (I was scared for it to complicate things further.)
2024-11-20 17:16:53 +0100 <dminuoso> So you dont have both A and SiteA flying around.
2024-11-20 17:16:43 +0100 <dminuoso> bwe: Right, DataKinds just cleans it up.
2024-11-20 17:16:31 +0100 <dminuoso> bwe: Say you can attach evidence onto a SiteVariant for your HasGeneral constraint.
2024-11-20 17:16:18 +0100 <dminuoso> bwe: So the idea is that with HasDict you can provide evidence for another constraint.
2024-11-20 17:16:16 +0100 <bwe> dminuoso: oh, I see, there's not too much difference in concepts with or without DataKinds
2024-11-20 17:15:31 +0100 <bwe> dminuoso: here's the latest version: https://play-haskell.tomsmeding.com/saved/9jXIcvKT
2024-11-20 17:15:05 +0100 <dminuoso> bwe: Lets keep the DataKinds, though.
2024-11-20 17:14:57 +0100 <dminuoso> With Haskell, there is a large portion about unlearning mindsets and learning new techniques, almost starting from scratch.
2024-11-20 17:14:43 +0100 <bwe> dminuoso: can we go back to complete the withDict first? I pretty much appreciate that DataKinds, though, later.
2024-11-20 17:14:36 +0100 <dminuoso> You can only lead a horse to the water.
