Won't it derive it with StandaloneDeriving?
Cheers,

I need to declare a Typeable instance for a type which has an argument of kind * -> *. GHC refuses to derive it.
What is a recommended way to go about it?
In particular, if I write the instance by hand, how important is the fingerprint, and how could I generate it?
