I don't know if (^) in particular is what is causing you problems, but IMO it has the wrong type; just as we have (!!) :: [a] -> Int -> a genericIndex :: (Integral b) => [a] -> b -> a we should also have (^) :: (Num a) => a -> Int -> a genericPower :: (Num a, Integral b) => a -> b -> a (or some other function name).
Seconded!
I've mentioned this before, but until http://hackage.haskell.org/trac/haskell-prime/ticket/118 is resolved we don't know where to discuss it (the haskell-prime or libraries list).
