Comment (by bgamari):

 Re comment:9:

 Oh dear, yes, that code is just non-sense. Sorry about that, it seems I
 should have read through it before hitting submit.

 Let's try again: The principle concern was that the current Typeable
 scheme provides a way for users to query the kinds at which a TyCon was
 instantiated via `Data.Typeable.splitPolyTyConApp`. The current New
 Typeable plan doesn't seem to provide any way to accomplish this.
