Unlocker<C> is a friend class that locks a mutex inside of LockBox<C> and acts as a lock_guard for that mutex. it also uses the -> and * operators to let you access members of the underlying C class
you can also make the Unlocker const so you can only access const members of C
anyway I'm proud of this C:
there is a wrinkle because there is no copy constructor since std::mutex has no copy constructor, but you could potentially get around this by wrapping the mutex in a std::shared_ptr
@SuricrasiaOnline so it's kinda like rust's idea of mutexes?
I like this, and agree, why the heck isn't it in std
@k thankfully it's not too difficult to implement yourself, you just need to piece together std::mutex and std::lock_guard together in a particular way
