In summary, I think we need to devise a way of better-documenting
class instances.
Haddock 2.7 supports documenting instance implementations; I don't know
how this works, but according to the Changelog it's available.
It's simple:
...
-- | Documentation for the instance
instance Monoid Foo
It's not for each method, just for the overall instance?  I was kinda
hoping to use it to be able to put runtime bounds on instances of some
classes :(
It's just for the overall instance at the moment. Haddock doesn't
document instance declarations separately.
