@emilazy:matrix.orgemilylike how TH makes order of declarations stuff weird as a trivial but gross example13:19:09
@mangoiv.:matrix.orgMangoIV how many GHC.Evil things does GHC use? 13:19:52
@teoc:matrix.orgTeo (he/him) idk Generics have been a headache on both of the industrial Haskell codebases I've worked on. Once you have records with more than say 16 fields, it gets pretty bad 13:19:55
@emilazy:matrix.orgemilyalso, Haskell is already two full-blown languages at the value and type level (and you can argue there's two or three more in the latter), another layer is just painful :P13:20:06
@emilazy:matrix.orgemilyno idea. but I wouldn't be surprised13:20:23
@mangoiv.:matrix.orgMangoIVbecause of compilation speed, right? 13:20:28
@teoc:matrix.orgTeo (he/him) yeah compilation speed 13:20:39
@mangoiv.:matrix.orgMangoIValso my comment was about GHC itself compiling slowly 13:20:44
@emilazy:matrix.orgemilyespecially since you often really want to for perf13:20:48
@emilazy:matrix.orgemilyor at least did back in my day13:20:52
@emilazy:matrix.orgemilyhave I mentioned I'm old lately13:21:06
