Get the current locale

I18n.candidates(with no option)

Requested Locales order by the priority. This method is added by Ruby-Locale for Ruby on Rails.

[#<Locale::Tag::Common: ja_JP>, #<Locale::Tag::Common: ja>, #<Locale::Tag::Common: en>]

I18n.locale (with inspect)

I18n.locale is set the result(Locale::TagList) of I18n.candidates(:type => :rfc).
This method is extended by Ruby-Locale for Ruby on Rails and returns all candidates as the Locale::TagList.

[#<Locale::Tag::Rfc: ja-JP>, #<Locale::Tag::Rfc: ja>, #<Locale::Tag::Rfc: en>]

I18n.locale (without inspect)

Locale::TagList(the result of I18n.locale) can behave like a single tag string to follow I18n.locale specification.
