Actually I think that Paul's assumption is flawed. The return type of
std::vector<T>::size isn't necessarily size_t, it's an unspecified unsigned
integral type (std::vector<T>::size_type). What's worse, that type can be
different for different T. So even when porting everything to size_t (which
might still be reasonable), user code would still have to deal with casting
things explicitly to avoid warnings.
