OK the new version of is_base_and_derived is checked in, along with stricter test cases, can someone who understands the implementation (I'm absolutely sure that I don't !), please provide an explanation to add to the header?
BTW I have looked at Terje's explanation, but the subtle changes to the Reni's implementation make in no longer quite applicable (although I may be missing something).
