Example: marc@localhost /tmp/qual $ ls; cat M.hs main.hs; ghc --make main.hs M.hi M.hs M.o main.hs -- module M ------------------ module M where import Data.List infixr 9 .!. f = "dummyf" (.!.) = (!!) -- module Main ------------------ module Main where import qualified M as M main = do print $ M.f -- (1) print $ M.(.!.) [1,2] 1 -- (2) -- ------------------------------- [2 of 2] Compiling Main ( main.hs, main.o ) main.hs:7:10: Not in scope: data constructor `M' (3) main.hs:7:12: Not in scope: `.!.' (4) Calling M.f (1) works fine whereas calling M.(.!.) results in the error messages. Is possible somehow? Can I find more information in the ghc docs? Marc Weber
