2021-08-14 13:52:40 yoctocell joins (~user@h87-96-130-155.cust.a3fiber.se)
2021-08-14 13:53:54 <Hecate> dminuoso: my point is rather than every datatype has different needs when it comes to pretty-printing/debugging, and a Show instance without a less principled couterpart is never the answer

2021-08-14 13:54:18 <Hecate> because you inevitably end up trying to fit your domain into the instance, which produces unlawful instances

2021-08-14 14:48:51 <maerwald> log-safe
2021-08-14 14:49:11 <kuribas> I'd say debugging is the primary usecase for Show...
2021-08-14 14:49:59 <maerwald> then you might not like the show utf8 proposal

2021-08-14 15:01:11 <joeyh> if a cabal file has a extra-deps github: line, and the git repository contains several packages, with a cabal.project in it that lists them all, will stack use those packages to satisfy other extra-deps?
2021-08-14 15:01:16 <keutoi> How constrained should I be w.r.t read . show == id ? Is it idiomatic that this hold?
2021-08-14 15:01:37 <tomsmeding> aarchi: doesn't the whitespace code build on a newer ghc? did you try, perhaps one in the 7 series that ghcup still has?
