Yeah, in spite of all the problems, unsigned values *are* needed for
certain things.  Java not having it was a *big* turnoff for me, because
certain things that ought to be simple become needlessly convoluted
(like parsing unsigned output from a C program, for example -- to
prevent silent data corruption you had to treat everything as strings,
which is a royal pain in Java).

Then again, a lot of things are needlessly convoluted in Java, so it's
not saying very much. :-P
