Good evening. I notice Data.Foldable ain't got no `foldl1'`, while `foldl'` and `foldl1` are both there. Is there a reason? What will it take to have it introduced? I refer to this specific version, which is to my understanding the latest to have been released: https://hackage.haskell.org/package/base-4.10.1.0/docs/Data-Foldable.html Thank you.
