You are correct, but I think it is better to advise the OP
to open the File in a block, as I demonstrated:

004:0> File.open("original") do |f|
005:1* puts f.readline
006:1> end

The main reason is that this will still close the file even if
an exception would occur (see IO.open for documentation).
