class C v where

A Module over a ring satisfies:

   a *> (b + c) === a *> b + a *> c
   (a * b) *> c === a *> (b *> c)
   (a + b) *> c === a *> c + b *> c

Methods

zero :: C a => v a

zero element of the vector space

(<+>) :: C a => v a -> v a -> v a

add and subtract elements

(*>) :: C a => a -> v a -> v a
