What stops Data.Foldable from having foldl1'?

[Andrew Martin]

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-Foldable.html
where they belong.
