A: Can I conditionally include class members without using #ifdef? There's nothing as elegant as `if constexpr`, unfortunately. However, it is possible to achieve the practical effects (member functions and data only present conditionally).

The good programmer has as many tools in their toolbox as they can get, and use the best one for the job, evaluating simplicity, performance, maintainability, reliability, etc. all jointly.

The documentation of `std::uniquelock` in the standard states that it's UB for the mutex do be destroyed while the lock still has a pointer to it. However, there is a way to dissociate the mutex from the lock: calling `release` on the lock. That resets the lock's... (more) |
