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.
