I oppose this change. You'd be better off not having unsigned
types at all than this mess, which was Java's choice. But then
there are more problems created.
What mess? The actual fix for issue 259 is simple, elegant, and
shouldn't require much code in the wild to be changed.
The difficulties and delays have all been associated with the
necessary improvements to VRP and constant folding, which are
worthwhile in their own right, since they help the compiler
generate faster code.
