So now, in Python 3, .keys(), .values(), even .items() all return these

Surely not. The fundamental behaviour of Python's data model hasn't
changed.
Poetic effect. Dramatic license. Blah blah. ;)
Repeat after me: "In Python 2, d.keys() returns a list of keys, so if I
want a list of keys in Python 3, call list explicitly list(d.keys())."
Actually, I would recommend `list(d)`, which also works the same in both 2 and
3.
