        ActiveSupport::Deprecation.warn(<<-MSG.squish)
          Calling fragment_cache_key directly is deprecated and will be removed in Rails 6.0.
          All fragment accessors now use the combined_fragment_cache_key method that retains the key as an array,
          such that the caching stores can interrogate the parts for cache versions used in
          recyclable cache keys.

        ActiveSupport::Cache.expand_cache_key([*head, *tail], :views)
