Subject: Hashes in 1.9 index

Since hashes in 1.9 retain their insert order, is there a built in way to get values by index as well as key?

For example:
h = { a: 17, b: 18, c: 19 }

puts h[1]
=> 19

Obviously that can't work, but there may be some other way I haven't found by looking through the docs? At the moment I'm using this:

class Hash
    def by_index( n )
      self.each_with_index { |item, index| break item if index == n }
    end
end

Just wondering.

Regards,
Iain
