[Haskell-cafe] Yampa / AFRPVectorSpace.hs

While studying the vector space class in AFRP, I encountered the following
strange code:

class Floating a => VectorSpace v a | v -> a where
   ...
    v1 ^-^ v2 = v1 ^+^ v1 -- (negateVector v2)


I have no idea why the (negateVector v2) has been commented out, but surely
this must be a typo?

Cheers,
Peter
