How about making the containers internally int64 and then offering both int and int64 interfaces in parallel?
The reason I am hesitant about this is following:
struct Item {
Vector<String> foo;
Vector<int> bar;
};
Now with 'int' size, this is 32 bytes. With 'int64', this grows by 16 bytes (50%) which would be wasted to store zeroes in 99.999% of cases...
Also, Vector having exactly 16 bytes has (very) subtle advantage, it is a 'nice' number (memory is allocated in multiplies of 16, adressing can be done with simple shift etc...
