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

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).
