Please bugzillize.

Generally this is the time to align the implementation with the book and 
also to put it in great shape. Walter and I needed to make a lot of 
microdecisions in the past weeks, which put pressure on the 
implementation. But I am happy to report that it generally feels that 
we're turning the right corners.

Regarding the recent debate regarding signed and unsigned numbers, I 
have great faith in value range propagation.
