I think a good solution would be something like

  function lines (filename)
    local f = assert(io.open(filename, "r"))
    return function ()
      return f:read() or (assert(f:close()) and nil)
    end
  end

so that we could use it without any other "preparation":

  for line in lines(file) do ... end

But I'm not sure whether such function belongs to the `io' lib or to
some extension library.
