Comment (by dreixel):

 Sorry for the delay; it's still in my to do list. His changes can be
 merged, though; perhaps it's best to do that earlier rather than later, to
 avoid conflicts. But please keep the ticket open; I'll close it once I
 make sure that the datatypes generated when deriving `Generic` have
 `Typeable` instances.
