Sure, but you have to explicitly enable this feature. In c++ you can use the oldest shit from twenty years ago and your compiler happily does its job. All my c++ books are full of “you shouldn’t use xy as it is deemed unsafe now, but of course you still can”.
If a “safe C++” proposal truly proposes a safe subset, then yes your C++ code would have to opt-in to doing unsafe things. For the purposes of this discussion of a safe subset … the point is moot.
Rust still allows people to do (basically) whatever they want via unsafe blocks.
Yeah but I have written a lot of Rust and I have yet to use a single
unsafe
block.Saying “but… unsafe!” is like saying Python isn’t memory safe because it has
ctypes
, or Go isn’t memory safe because of itsunsafe
package.See my reply to funtrek’s reply.

It’s not moot. The Safe C++ is opt-in to safety. It has to be because otherwise it wouldn’t be compatible with existing C++.
That’s a laudable difference /s. Using Rust is also an “opt-in” option.
