Definitely the big reason from my perspective to make more things
comparable is to allow their use with dictionaries and sets. For that
usage, the comparison could even be compiler dependent (or even execution
dependent) but I'm sure that someone would build code that depended on
properties of
I just realized that the sortBy function already allows you to sort a list
by any sort criterion of your choice. Which removes some of my concerns in
the previous post.

It seems like a minor detail that may come as a matter of course, but I'd
like to request that Bool's should also be comparable. If Bools are not
comparable but you embed a Bool inside a tuple or a List or a Record, that
makes the larger type also not comparable. Unless you decide to ignore

Regarding (2), I was not aware of this. Cool =)
Having a deriving-esque way to generate encoders and decoders automagically
would be great, and would go a long way in solving the hassle. (2) would
also make my life easier.
