ExitCode consistency
Haskell 98 says
Computation system cmd returns the exit code produced when the operating system processes the command cmd.and
The exact interpretation of code is operating-system dependent.However, on Unix systems system "exit 3" >>= print prints ExitFailure 3 under ghc and hugs, but ExitFailure 768 under nhc98, despite both being the same operating system.
It may not be possible to fix this within the boundaries of the report, but Something Must Be Done somewhere.
Additionally, the report says
The value exitFailure is equal to exitWith (ExitFailure exitfail), where exitfail is implementation-dependent.while operating-system dependent seems better than implementation-dependent.
