Well, it has, I double-checked that the missing "Iterator" above was
already on my branch, therefore my IRC comment pointing you to qom-next.

Other than that you only seemed to discuss design alternatives, for
which neither you nor Daniel provided any actual patch I could've
applied. While I regularly do style fixups myself, and with the series
missing -rc0 also functional fixes, posting a diff for review/record, I
do not see redesigning a 6-patch series as something I can silently do
last-minute without full respin, for which -rc1 did not leave time.

There was a v3 with iterators, and Pavel pinged v4 twice, I did once
too, and the last delay after getting the series to work was only due to
me inserting Daniel's test case (legit hardfreeze material), so ...

... yes, from my perspective any such cleanups can be done post-2.5.

Please note that both patch 6/7 (included) and 7/7 (not in this pull)
enhance the iterator, so follow-up patches should be based on qom-next
please.

Thanks,
Andreas
