claudiob fbda46758b Revert #26826 and add documentation ... This reverts commit a01cf703 as explained in the comment to #26826: Realized that this PR caused the following warning in Travis CI: ``` /home/travis/build/rails/rails/activesupport/lib/active_support/dependencies.rb:293: warning: loading in progress, circular require considered harmful - /home/travis/build/rails/rails/activesupport/lib/active_support/core_ext/hash/indifferent_access.rb ``` Indeed, `active_support/core_ext/hash/indifferent_access.rb` **needs** to require `active_support/hash_with_indifferent_access.rb` in order to access the class `ActiveSupport::HashWithIndifferentAccess`. The other way around, though, is not _strictly_ required, unless someone tries (like I did in the [gist above](https://gist.github.com/claudiob/43cc7fe77ff95951538af2825a71e5ec)) to use `ActiveSupport::HashWithIndifferentAccess` by only requiring `active_support/hash_with_indifferent_access.rb` without first requiring `active_support/core_ext/hash/indifferent_access.rb`. I think the solution to this is to revert this PR and instead change the documentation to explicitly state that **developers should not require 'active_support/hash_with_indifferent_access'** if all they want is to use `ActiveSupport::HashWithIndifferentAccess` – instead they should require `active_support/core_ext/hash/indifferent_access.rb`.		2016-10-21 22:55:51 -07:00
