Yes, of course. That's why I'm wondering if turning dict keys into a set is slower now.
2. IIRC the new dicts are no(t significantly) slower than the old dicts, however they use less memory, and iterate faster
The iteration order is actually a side-effect of implementation details, the original goals were a more compact representation and a faster iteration: https://mail.python.org/pipermail/python-dev/2012-December/1...
