Expressions joined with `&&` are better asserted separately, so that it is clear from the failure message which expression is false. Also, `unsigned long` may not be enough for `ptrdiff_t`, e.g., Windows. Saying that `ptrdiff_t` can be larger than `SIZE_MAX` means that `PTRDIFF_MAX` is larger than `SIZE_MAX` and `ptrdiff_t` is sufficient to represent `SIZE_MAX`, otherwise if `PTRDIFF_MAX` is smaller than `SIZE_MAX`, `diff` will always be smaller than `SIZE_MAX` as well. `diff` could be equal to `SIZE_MAX` only if `PTRDIFF_MAX` is equal to `SIZE_MAX` and these assertions would pass, but I don't think there is any platform where that is the case.
