Like Gabriele said in the other thread, they seem to already...

$ cat test.rb
lukfugl@falcon:~$ cat test.rb
class MyArray
  include Enumerable

  def initialize( *ary )
    @ary = ary
  end

  def each
    @ary.each { |el| yield el }
  end
end

def test( ary, *sequence )
  puts "### #{ary.class}, #{sequence.inspect} ###"
  ary.each do |el|
    puts el
    case sequence.shift
    when :next then next
    when :retry then retry
    when :redo then redo
    when :break then break
    end
  end
end

ary1 = [ 1, 2, 3, 4, 5 ]
ary2 = MyArray.new( *ary1 )

test( ary1, :next, :retry, :next, :next, :redo, :redo, :break )
test( ary2, :next, :retry, :next, :next, :redo, :redo, :break )

$ ruby test.rb
