I can't remember a time when signed hex, oct, or binary representation
wasn't a major inconvenience, let alone something desirable.  Don't get
me started about hex(id(object()))!  I typically use hex for addresses
and bit fields, binary for bit flags and other bit twiddling, and oct
for OS/file system interfaces.  In none of those cases do you actually
need or want signed values.  IME.
