Subject: [ruby-core:26191] [Feature #2065] An ancestors iterator

Issue #2065 has been updated by Roger Pack.


You could write your own method:

class Object
  def ancestors_cached
    @ancestors ||= ancestors
  end
end

Would that be sufficient? (It's harder to implement that in core since it would need to be invalidated whenever a class hierarchy changes).
