This doesn't compile for me. It complains that the last statement in a 'do' construct must be an expression...what gives?
There's a layout error - the statements in the do should be left-aligned: go' f = do h <- openFile f ReadMode text <- hGetContents h let c = head text c `seq` do { hClose h; return c } It's probably caused by different systems having different tab-settings.
