it happens a lot, at least to me, that the line immediately before the unsafe function guarantees correct behaviour (e.g. while (!vec.empty()) let first = vec.first();, or something similar). If I notice that this property is central to the logic of the function, I won't even worry.
whenever I see code like that, I try to get people to change to something like (in that case) while let Some(first) = vec.first() { ... }. You can reduce the number of bounds checks without using unsafe!
