Eric's post shows me how to get that particular example solved. But my real concern is, when my code (inside some deep loop) calls solve, I want to know (a) if it returns an answer, that answer really is a solution, and (b) if it returns an empty list, there really is no solution.
So this example shows that (a) is sometimes false. And when is (b) true?
