[Haskell-beginners] Expressing the idea of a group in Haskell

[.]

Thanks to everyone for your explanations; and sorry about the group
blunder ;)  of course Brent is right, I should have said "R_+^*" plus
multiplication.
I will keep an eye on what the Haskell people do about Hierarchies of
mathematical classes.

Cheers
Christian
