  ActionView::Template is now completely independent from template
  storage, which allows different back ends such as the database.
  ActionView::Template's only responsibility is to take in the
  template source (passed in from ActionView::Path), compile it,
  and render it.

Now that we have a separate internal rails_to_json, use a separate circular reference stack instead of sticking it in the options hash

    Example: ActiveSupport::JSON.backend = "JSONGem"

  All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode().  Use of #to_json is not recommended, as it may clash with other libraries that overwrite it.  However, you can recover Rails specific functionality
  if you really want to use #to_json.

    gem 'json'
    ActiveSupport::JSON.backend = "JSONGem"

    class ActiveRecord::Base
      alias to_json rails_to_json
    end
