You should alwasy check if get succeeded.

  prompt = <<PROMPT
  Make your selection from the list below: \n
  a) foo
  b) bar

  PROMPT

  while (print(prompt); ans = gets)
    handle_action(ans)
  end

Or even better if you can use readline:

  while ans = readline(prompt)
    handle_action(ans)
  end

No way to do it.  If you believe STDIN is connected to tty, you
may want to do STDIN.reopen("/dev/tty").
