Hash#key for 1.8.6

Greetings,

I am trying to make my 1.9.1 source 1.8.6 compatible. I recognized that there's no Hash#key method. Any idea or method how to solve that?

Thanks!

Tobias

In ruby 1.8 that method is called index.

Use Hash#index, or require "backports" and most of the API changes from 1.8.6 to 1.9.2 will be backported and available in Ruby 1.8.6 (including Hash#key, of course).
