   I guess you want to run ghci or hugs, not ghc.

   You should be able to implement this easily. I'm not running=
 UNIX/Linux here, so I can't test it, but this should work fine=
 just by specifying the correct executable path. The only problem=
 I'm aware of is that the first line (the #! line) might be=
 included in the input piped into the program, which means that=
 you'll have to run it through a filter. But that filter should=
 be very easy to make using awk or something like that. You could=
 even make it in Haskell, if you want, and you could make it=
 prepend the "module" header, too, for convenience.
