Aha!  And this got me to think of a similar way to do it that is even
more C-like:

  def main
    puts foo
    puts bar
    exit(0)  # or it could be this:  return (0)
  end

  def foo
    return "foo"
  end

  def bar
    return "bar"
  end

  END { exit(main) }
  # ... or without the END block as long as the last line of
  # the file is   exit(main)
  

Thank you very much!
