auto insert value to dict, when value is not in dict, is what defaultdict
try to do.
Behaviour you are deliberately avoiding by calling `get`, since that
explicitly behaves the same way that it does for dicts. You're doing
two different things through two different interfaces with two different
specs. Why are you expecting them to have the same effect?
