Comment (by goldfire):

 I don't see a problem thus far. But as I said in my previous comment, you
 may need to unify that result kind with `*` in the datatype case
 somewhere. Perhaps a `_ <- unifyType blah blah (typeKind res_ty)
 liftedTypeKind` would do the trick, but perhaps something more elaborate
 is necessary. I do think you're pushing in the right direction, though.
