I've had my fair share of annoyance from situations like "I have between one and four hard-coded insertions into this vector, but the compiler yells at me if I try to store the resulting size in an int". Also, tangentially related is the signed/unsigned business which tends to get in the way frequently. For example, OpenMP 2.0 (the only OpenMP version you get to use with MSVC) requires loop indices to be signed, but both std::vector::size and std::vector::operator[] deal with unsigned integers. Casts guaranteed!
