      std::vector<std::vector<bool>> is how I stored the representation of a play field for a Tetris game I made once.

      auto v = std::vector<bool>(8);
bool* vPtr = v.data;
vPtr[2] = true;
// KABOOM !!!

      I’ve spent days tracking this bug… That’s how I learned about bool specialisation of std::vector.
