To regenerate simple array

>> test_obj = ["blah","blah"]
=> ["blah", "blah"]
>> YAML::dump test_obj
# produces
--- 
 - blah
 - blah

How about something HARD

>> test_obj = Hash.new
=> {}
>> test_obj[:production] = {}
=> {}
>> test_obj[:production][:main] = [["margin_rates", []], ["credit_tier_editor", ["show"]], ["override_editor", ["show","new"]]]
=> [["margin_rates", []], ["credit_tier_editor", ["show"]], ["override_editor", ["show", "new"]]]
YAML::dump test_obj
# produces 

---
:production:
  :main:
  - - margin_rates
    - []
  - - credit_tier_editor
    - - show
  - - override_editor
    - - show
      - new
