Re: openfile :: String -> String

[Jan Skibinski]

        Angus is right on the track. I would only modify
        it slightly:

        content_xxx :: String
        content_xxx = (unsafePerformIO . readFile) "xxx"

        From Hugs perspective content_xxx is a constant.
        Your may easily demonstrate it this way:

        :!echo blah > xxx
        content_xxx ==> "blah"
        :!echo Hello > xxx
        content_xxx ==> "blah"
