Feedback on some code please (Read A File Into A List Tail First)

This is some code which I created to read a file into a list tail first. In this case, I need to search for something in the file from the end first so this works out perfectly for what I need.

def file_into_list_tailfirst(file) do
  :io.setopts(:standard_io, encoding: :latin1)!(file)
  |> IO.binstream(:line)
  |> Enum.reduce([], fn(line, acc) -> [line|acc] end)

Would appreciate any comments anyone cares to share.
