Can you verify that this is not going to actually change the I18n stored data?

```ruby
>> x = I18n.translate(:'date.order', :default => [])
=> [:year, :month, :day]
>> x.map! &:to_s
=> ["year", "month", "day"]
>>  I18n.translate(:'date.order', :default => [])
=> ["year", "month", "day"]
```
