When I say 1/100 C++ programmers are able to properly understand aliasing rules, and confidently use `restrict`, I was already talking about professional senior programmers. If you consider the whole set of C++ programmers that would drop to 1/1000. We can discuss the numbers, but from my experience working in some very low level areas where you would expect C++ (or C) developers to know that kind of thing, I would say 1/10 would understand really how `restrict` works. On that basis, I would say that, yes, C++ does not a good job at handling the aliasing of memory locations, since the required mental mumbo jumbo required to declare aliasing properly is too consuming for even experts.
