I think Beni has a very nice idea here, especially for people who can't
visualize 2's-complement (not mentioning Guido by name <wink>).

I just got another idea: use 0x1234 for 0-filled numbers and 1xABCD for
1-filled ones.  That way you impose no restrictions on what follows the
prefix and keep backward compatibility.  0xFFFFFFFF stays a 2^n-1
_positive_ number, as it should be.  The look of 1x is weird at first but
it is very logical...
