catch_unwind [...] does not guarantee the program is in a consistent state afterward, since Drop impls may have run partway through.

Wait, what? Any more details about this, I've never heard about that before. Partially run Drop impls sounds like a big potential for undefined behavior, how could catch_unwind possibly cause that?

EDIT: The more I read this article, the more AI-generated it looks and so I'm sort of wondering if the above quote is just complete bogus.
