I think this analogy is just terrible. A book != code. Well, certainly a novel, in which you're not re-reading the same sentence several times over, flipping 100 pages forward, then 90 pages back, etc. I can actually think of certain ways in which a non-fiction book could be usefully 'syntax highlighted'.
