I would also guess that:

  def println(*x); x.each { |y| print y }; print "\n"; end
  class Foo < Array
    def to_s; return inspect; end
  end
  println Foo[1, 2, 3] # prints "[1, 2, 3]\n"
  puts    Foo[1, 2, 3] # prints "1\n2\n3\n"

Though I don't think I've seen anyone particularly attached to puts's
behavior here (see [ruby-talk:28052] and following).
