Fwiw there is at least some strong user interest in this feature if anyone is thinking of working on it. I find myself checking on its progress pretty often, and would use it in our production codebase in a heartbeat.
Rather than waiting, it is perhaps more pragmatic to go with a custom Prelude, which one can have now, even for versions of GHC/base, that won't have the feature in question: {-# LANGUAGE NoImplicitPrelude #-} module Main (main) where import ListPrelude import qualified Data.Foldable as F main :: IO () main = do let { one, two :: Int; one = 1; two = 2 } -- OK print $ length [one, two] print $ F.length (one, two) -- Type error -- print $ length (one, two) -- Viktor.
