I am someone who has written a lot of Rust, enough C++ to know better, and is loosely familiar with Julia. I think its awesome people are becoming aware of the benefits of writing Rust. In the same breath, this is missing probably the biggest advantage. These checks should be compile time guarantees. Maybe the language will move that way? This is my opinion and it is a philosophical one but opting in and out of safety checks means you don't care how sturdy your software is until you personally have observed an error. In a lot of cases that's "too late" for production.

For debugging after an issue is found this is maybe helpful though.
