Now that I know ARGF exists . . .

http://www.danvk.org/wp/?m=200701 reports the following:

  ARGF is a great crutch for Perl programmers who miss typing while(<>)
  {...}. It opens each input file left in ARGV and yields each line. If
  there�s no input files left, it reads STDIN and yields each line it
  gets there. Many, many programs do their work in an ARGF loop.
