i strongly agree. ignoring of first line if it starts from "#" must be added to all Haskell realizations
I think Frederik is suggesting that under Windows, System.Cmd.rawSystem and friends should examine the start of the file it is asked to execute, looking for #! and then try to simulate Unix behaviour. That might help some things, but it won't always work, so may not be worth it. Haskell implementations already ignore lines starting with # if the file is a literate script.
