 I do it this way using each().

def my_downto2(final=2)
      (final..self).to_a.reverse.each do |i| yield i end
end

But I am still uncomfortable that I  have to use #to_a followed by 
#reverse to do the trick. Besides using while loops what is the best way 
to add a new method of #downto?

Thanks,

Li
