Just tried to use `activesupport`, it's not working well for us. The [Array.to_sentence](https://github.com/rails/rails/blob/v3.2.11/activesupport/lib/active_support/core_ext/array/conversions.rb#L11-L20) uses I18n translate method, in ZAS, we use ZendeskAppsSupport::I18n to read our translation files. If we call the to_sentence method we get a missing translation error like this: translation missing: en.txt.apps.admin.error.app_build.invalid_location because the global I18n gets called first.
