Are you telling me that no compiler optimizes this? Why?
Well there are containers that store booleans in single bits (e.g.
std::vector<bool>- which was famously a big mistake).But in the general case you don't want that because it would be slower.
Why is this a big mistake? I’m not a c++ person
The mistake was that they created a type that behaves like an array in every case except for
bool, for which they created a special magical version that behaves just subtly different enough that it can break things in confusing ways.Could you provide an example?
