Neither does really work: if some package is rewritten to expect .items() to be an iterator, one would have to turn on that -3 option if using that package. OTOH, some other package used at the same time might expect just the opposite. > I don't see a path forward that doesn't involve something painful, > so long as 3.0 is going to be the clean break. There would be if there was some version which already had .items as an iterator, but still supported .iteritems as well. Let's call that version 2.99. It would be compatible with 2.6, but also with 3.0.
