Subject: Wrong statement in Ruby 1.9 keyword doc on ruby-doc.org

Hello,

I've found there's a mistake in the keyword documentation for Ruby 1.9
on ruby-doc.org. For "return" one code example is:

  def three
    return 3
  ensure
    puts "Enjoy the 3!"
  end

  a = 3    # Enjoy the 3! #<=====WRONG
  puts a   # 3

where the marked line does not show "Enjoy the 3!". I think that line
has to be
  a = three
.


Btw., you can pass an argument to the "next" keyword:

irb(main):001:0> ary = [1, 2, 3]
=> [1, 2, 3]
irb(main):002:0> ary1 = ary.map{|x| next;x + 1}
=> [nil, nil, nil]
irb(main):003:0> ary2 = ary.map{|x| next(95);x + 1}
=> [95, 95, 95]
irb(main):004:0>
