Hi, I was playing around with runhaskell (runghc to be precise), and I discovered the limitation wherein you have to use the file suffix ".hs". Don't get me wrong, runhaskell is great, but if you didn't have that restriction it would make haskell much more attractive to many programmers who write standalone scripts. Of course it's always possible to do e.g. (file: hello) #! /bin/sh runhaskell Hello.hs (file: Hello.hs) module Main where main :: IO () main = putStrLn "hello, world!" but that's pretty inconvenient. What I'd like is: (file: hello) #! /usr/bin/env runhaskell module Main where main :: IO () main = putStrLn "hello, world!" which is _almost_ doable; you have to name the file "hello.hs". What would really be optimal is something like (file: hello) #! /usr/bin/env runhaskell -fglasgow-exts -- extra arguments to runhaskell !# module Main where main :: IO () main = putStrLn "hello, world!" Looking through the mailing list I see something from May 2005 on this topic about adding the equivalent of gcc's "-x" option to ghc. What's the status of that? Cheers, Mike
