I think I've said before that it would be nice if we had a specific class
for debugging displays, given that Read/Show are generally oriented toward
serialization. Sadly, this would end up requiring a lot of repetition,
since you couldn't sanely fall back on a default Show instance to get a
notional Gist (or whatever) instance.
