hi, is there (in Haskell) a function like existFile :: FilePath -> IO (Bool) ? Thanks!
Using such a function is generally a bad idea because of race conditions.
however, real world programs use those tests since you don't need to care *everytime* about race conditions. (of course using this existFile before creating a temporary file is wrong, but existFile has *many* other applications)
