I do use lengths in arithmetic sometimes, and that leads to silent bugs currently. On the other hand, since going from 16 bits to 32 and then 64, in my user-side programs, I had a flat zero bugs because some length was 2^{31} or greater -- but at the same time not 2^{32} or greater. So, in D, I usually `to!int` or `to!long` them anyway. Or cast in performance-critical places.
I had a similar bug in C++: the find function returns npos sentinel value when not found, it was assigned to uint and then didn't match npos on comparison, but it would if they were signed.
