Fully agree. Lot of pogrammers misunderstands signed types which results in different bugs when combining signed with unsigned.

More importantly though, not having unsigned types, as in Java, means that we have to use 16-bit int to store a byte, 32-bit int to store a 16-bit unsiged etc.

Btw, if you check any C code, you'll notice that is vast majority of cases negative values of int are actually invalid from the business logic point of view.
