Ok, here's the new proposal.
readProcess :: FilePath -- ^ command to run -> [String] -- ^ any arguments -> String -- ^ standard input -> IO String -- ^ stdout + stderr

MayFail seems to be attached to the wrong one here. 'readProcess' is the one that might fail, the second actual call always succeeds but returns an error code. I think readProcessWithExitCode is better. John -- John Meacham - ⑆repetae.net⑆john⑈
