Yea, I don't think simplehash is the best choice here. It's worthwhile
to use it for performance critical bits, but using it for everything
would just increase code size without much benefit. I'd tentatively
assume that anonymous record type aren't going to be super common, and
that this is going to be the biggest bottleneck if you use them.
