That’s right, the keyword enables additional operations, namely those that can’t be checked — which one might even call “unchecked operations” to justify the keyword.

My problem with the word “unsafe” is that many people seem to think unsafe code blocks necessarily have security issues. Hence the bullying of library authors even in cases where the authors did their homework.

Anything about the mechanics of the implementation is a second-order detail compared to that, as far as I’m concerned.
