I don't expect a pair< pair<int, int>, pair<int, int> > to be frequently
refactored into an int[4]. So no, I don't think that it should necessarily
have the same hash value as an int[4]. Similarly, I don't think that vector<
vector<int> > should necessarily have the same hash value as its flattened
vector<int> counterpart.
