Can GHC be invoked somehow via the #! mechanism? Put another way, is there a GHC analogue to runhugs?
Well, ghc now has an -e flag to evaluate stuff directly from the prompt (e.g. ghc -e Main.main Main.hs). But you can't execute shell-scripts from a shell-script with #! so you can't just put it in your Haskell module. Neither can you use the binary directly since you can only give one argument to programs executed with #! and you need both -e and -B.
Aha! I knew there was something else. However, I just tried it on a recent Linux (RedHat 9) and it seems to accept nested #! scripts. There's a rather annoying limit on the length of the #! line, too. Cheers, Simon
