[Haskell-beginners] hide Perl code inside Haskell program

[Hong Yang]

I was trying to hide Perl code inside Haskell program like the following:

> module Main where

> import System.Environment (getArgs)
> import System.Cmd

> main = do
>               args <- getArgs
>               rawSystem pl args
>            where pl = "#!/usr/bin/perl\n" ++
>                           "print \"testing ...\n\";"

The program can run, but generates no output at all. Can someone tell me any
other tricks which might be missing? (Do we need to use pipe here?)

Thanks,

Hong
