UB says at one point:

> Would that we had such a crystal ball

And then it seems like he actually found his crystal ball, because in the very next question he refers to things that have not yet occurred in the conversation:

> interpreting your rewrite (below)

And later:

> In your solution, which we are soon to see below

This makes it somewhat confusing to read, with answers being based on counterpoints that will only have been made in the future. (Which, I suppose, is similar to the problem Ousterhout has with UB's PrimeGenerator example.)
