Typeable TypeNats
It would be useful (the case I have at hand is for some scenarios involving checking of physical dimensions) to be able to combine the Data.Dynamic story with the GHC.TypeLits story.
A Typeable instance for every Nat is the sticking point.
(I do not know if this is even theoretically possible.)
