I think this really brings up the question of what `Show` should be used for. If the goal is to be simple serialization with `Read` as the inverse[1], then this is clearly a nonsense instance and shouldn't be included.

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.
