Using GHC 7.6.3, if I have ``` import Data.List main :: IO () main = return () ``` then I get a warning as expected. ``` % ghc -fforce-recomp -Wall test1.hs [1 of 1] Compiling Main ( test1.hs, test1.o ) test1.hs:2:1: Warning: The import of `Data.List' is redundant except perhaps to import instances from `Data.List' To import instances alone, use: import Data.List() Linking test1 ... ``` However, if `import Data.List` appears on the first line, i.e. with no blank line at the top of the file ``` import Data.List main :: IO () main = return () ``` then I get no warning. ``` % ghc -fforce-recomp -Wall test1.hs [1 of 1] Compiling Main ( test1.hs, test1.o ) Linking test1 ... ``` Can anyone explain this?
