I chose to do the ad-hoc check rather than yet another tree walk. 1. It's faster to run and easier to read. 2. This error came from looking at real code. It happened twice, so I think the best estimate for other uses that happened zero times is in fact zero. 3. I couldn't think of other places to put the cast, given the restrictions on `testedNode` just before the new code.
