maximum and minimum are not good consumers in ghc 9.8.1

Motivation

maximum and minimum are not good consumers in ghc 9.8.1 which results in poor performance. I think this is true in earlier ghc versions also.

Program that demonstrates this (first do: cabal install --lib list-fusion-probe) :

{-# OPTIONS_GHC -Wall #-}

import Data.List.Fusion.Probe (fuseThis)

-- must compile with -O for fuseThis to work
main :: IO ()
main = print $ maximum $ fuseThis ['a'..'z']

Put the preceding in a file called enh.hs

% ghc -O enh.hs

Change "maximum" to "minimum" to see this.

Proposal

Change maximum and minimum to be good consumers which will improve performance.
