DrIFT can derive 'rnf' or reduce to normal form for arbitrary classes
which is similar to deepSeq, in fact does anyone have a good description
as to how they are different?

(guess who finally decided to learn about imp params :P)
this looks like a bug to me, but of course i may be wrong.
consider these definitions:

in the cannonical sort with implicit params, i we write something like:
mySort :: (?cmp :: a -> a -> Ordering) => [a] -> [a]
mySort [] = []
mySort (x:xs) = insert x (mySort xs)
where insert x [] = [x]
insert x (y:ys)
| ?cmp x y == GT = y : insert x ys

The reason for using ForeignPtr is to attach free functions.

I've tried to use DiffArray recently and it is terribly slow. I
