I compile the programs, instead of trying to run them as scripts. Is there any reason you prefer to interpret the scripts? I'm not saying it's not a legitimate thing to do, just wondering why you prefer to do it that way.

Hello,
What is the proper technique for creating a Haskell script on a Unix system?
e.g. with Perl I do
#!/bin/sh echo DEFANGED.348224 exit #!/usr/bin/env perl print "hello world\n";
or
#!/usr/bin/perl print "hello world\n";
I tried
$ cat test #!/usr/bin/env runhaskell module Main where main = do putStrLn "hello world"
But that doesn't work:
$ ./test Warning: ignoring unrecognised input `./test'
<interactive>:1:73: Failed to load interface for `Main': Use -v to see a list of the files searched for.
When I use "runghc" I get the same error.
If I change the first line to "-x hs" then the error is:
ghc-6.6: unrecognised flags: -x hs Usage: For basic information, try the `--help' option.
because the #! mechanism only allows a single argument. Thoughts?
Thanks,
Frederik
