I don't mean to say that C++ is in any way without faults. If performance is crucial, that can definitely be a reason to forgo some of the guard-rails, and then you're on your own.

I guess my issue with the "C++ is unsafe"-trope, is that it usually (in my experience) comes from people not having heard of all the guard-rails in the first place, or refusing to use them when appropriate. They write C++ as if they were writing C, and then complain that the language is unsafe when they've made a mistake that is easily avoided using stl-containers.
