I had a look now and I agree that it looks like plain English is the defacto standard for the PANIC comments, so I will update them. But, I wonder what people think about this. IMO it makes sense to have SAFETY and PANIC comments as rigorous proofs (where practical and possible) to match the level of work the compiler does for us in the infalliable areas of the code - if an issue occurs, unsafe or panicking code is often the root cause IMO. Writing these in plain English is easier to read but also harder to verify that the proof is correct and harder to verify if there are any implicit assumptions. I see there are some guidelines about SAFETY: comments but not about PANIC: comments in Documentation/rust/coding-guidelines.rst.
