Comment(by vivian):

 Replying to [comment:7 vivian]:
 > * I can figure out the resulting type using `mkAppTy` but that takes
 `Type`s not `TyThings`.  What is the correct way of getting a `Type` from
 a `TyThing`?
 >
 After some perusal, I have found `mkTyVarTy`, `mkTyConTy`, and so on which
 can be used to turn `TyThing`s into `Type`s.  Is this the correct way?
