Yes, definitely.
Yes, I mentioned this to Don previously when he published his popen code. I think he agreed.
I'd changed, but not pushed out, process-light:
readProcess :: FilePath -- ^ command to run -> [String] -- ^ any arguments -> String -- ^ standard input -> IO (Either (ExitCode,String) String) -- ^ either the stdout, or an exitcode and any output
You don't need the Either. ExitCode already covers the case when the process terminates successfully. Duncan
