memory safety isn't really much of a problem with modern C++. We have the range library now for instance. What's nice about modern C++ is you can almost avoid most manual loops and talk at the algorithm level.

Are we talking about the same range library? The one that showed up in C++20 and is basically just iterator pairs dressed up nicely? The one where somehow the standard thought all memory safety issues with iterations could be summed up with a single “borrowed” bit? The one where instead of having a nice loop you can also build a little loop body pipeline and pass it as a parameter and have exactly the same iterator invalidation and borrowing problems that C++ has had since day 1?

Ranges are not memory safe. Sorry.

And yet in practice, it's been less than a week since a major CVE in Chromium due to memory unsafety: https://chromereleases.googleblog.com/2026/02/stable-channel...

Having a checklist of "things not to do" is historically a pretty in effectiveway to ensure memory safety, which is why the parent comment was asking for details. The fact that this type of thing gets dismissed as a non-issue is honestly a huge part of the problem in my opinion; it's time to move on from pretending this is a skill issue.
