Every time I stumble upon Scrap Your Boilerplate again (a.k.a. Data.Data) I feel sad that it didn’t take off the way GHC.Generics did. #haskell
@ttuegel Actually, GHC Genetics are fast enough for automatic Storable instances. Almost no degradation from hand-rolled code without a chance for segfaults.
@dpwiz Generics is fast as long as everything gets inlined the right way. Ensuring that inlining happens correctly as a project scales is, in my experience, a cost that doesn’t scale well.
@ttuegel At least it has a chance to be inlined. SYB is slow however you slice it.
@dpwiz Yeah… I wouldn’t recommend GHC.Generics anywhere that performance matters, either.
