While we're at it, what about adding even more classes, like "group"

Only ambition required :-).

--- go nuts.
There is a Math Prelude, but perhaps one can simplify and divide into
parts that refines the current Prelude, and stuff built on top of a
refined Prelude. The problem with the current one is that for example
Num claims (+), insists on Eq and Show, and there is no way to get
rid of those requirements. So inserting some classes, like
AdditiveSemiMonoid would be less ambitious than writing a whole new
algebra oriented Prelude. Perhaps a better chance of success.
