using haskell as a shell language

[Hal Daume]

Hi,

As we all know well, we can write scripts like:

#!/usr/bin/perl -w
print "foo"



and whatnot.  i'd like to be able to write something like:


#!/usr/local/ghc/bin/ghc
main = do putStrLn "foo"



and whatnot, even if I have to explicitely say something like:

#!/usr/local/ghc/bin/ghc
module Main(main) where
main = do putStrLn "foo"



it doesn't really matter.  but i'd like to be able to write something
like this, chmod +x it and be able to execute it, interpreted.

i have *no* idea what the semantics of #!... is in shell scripts, so i
don't know if it's easy or hard to hack something like this together,
but if anyone has any pointer (or if anyone's done something like this
before), please please please let me know.

thanks!

 - hal
