| 2026-01-26 15:16:14 +0100 | <ags> | What advantage does `Servant` have over `Yesod`? I understand that `Servant` is able to automatically generate a lot of stuff but it seems to me that `Yesod` is able to achieve the same type-safety via TemplateHaskell and QuasiQuotes. Am I missing something? |

| 2026-01-26 14:59:11 +0100 | <haskellbridge> | <Man of Letters (Mikolaj)> Leary: thank you; spot on, too bad, yeah, I guess I may try to use the internals of the libraries I use to write versions of some of their functions specifically for "(a, b), but it's a shame; if I had "Fst"and"Snd` maybe constraints in my own code would suffice, but probably these would trigger the same unsoundness that GHC assuming them does |

| 2026-01-26 14:49:16 +0100 | <Leary> | For that specific example I would say "just don't give `lengthT` that type", but I doubt that advice generalises to your actual code. |
| 2026-01-26 14:47:47 +0100 | <Leary> | Man of Letters (Mikolaj): Relevant issue: <https://gitlab.haskell.org/ghc/ghc/-/issues/7259>; these "eta-rules" aren't sound in current GHC due to some type family foibles, but there's no issue with taking them as explicit constraints or matching on `T`, if either help. |
