Alexandre Courbot spends most of his time working on the kernel doing codereviews. Recently, he's been wondering about what the standards should be forwhen Rust code is allowed to panic, and how it should do error handling moregenerally.

He brought along a collection of trickycases that he had run into recently to prompt discussion.
