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.
I think that introducing foldl1' would be a step in the wrong direction.
It's unfortunate that Foldable was brought into base with the partial
functions foldl1, foldr1, maximum, and minimum. If anything, I would argue
that we should try to relegate them to
http://hackage.haskell.org/package/semigroupoids-5.2.2/docs/Data-Semigroup-F...
where they belong.

foldl1 on Foldable is not a friendly function :) You want Data.Foldable1 https://hackage.haskell.org/package/semigroupoids-5.2.1/docs/Data-Semigroup-... Note that this one is friendly. On 07/03/18 02:30, sonne wrote:
