Proposal: Remove Show and Eq superclasses of Num

I found this proposal interesting. Indeed, as far as I can remember, almost
every instance I did in the Num class forced me to do a couple of instances
more (Eq and Show) that I have never thought to do. Sometimes, even there
was no way to do them (in a reasonable way).

Well, this is just another opinion.
